A more detailed list can be found here. There is also a video!

I just want to try it out!

We've got a Sandbox ? !

Browser support

These are the minimum versions of major browsers currently supported by Indico. We try to target all modern browsers as much as possible, but only issues detected on those will be considered at critical level.

Firefox	Chrome	Safari	Edge
78+	83+	13+	17+

However, if you have an issue with a browser on this list, please feel free to open a bug report.

Getting Indico

Information on how to get the latest release can be found at the project's web site. There are installation guides for different systems available in the project's documentation.

Contributing

Indico is the result of the collective work of more than 100 different developers, translators and usability specialists of many nationalities. You can be the next one - read our Contribution Guide if you'd like to help out.

You don't need to know how to write code in order to help!

Roadmap

The full roadmap is available on the project site.

Community

The main meeting points for the community are:

the Project Forum;
the Chat Room (#indico on Freenode or on Matrix).

We follow CERN's Values and the principles established by CERN's Code of Conduct.

History

This software project was initially funded by the European Union's FP5 programme ?? , in what was called the Integrated Digital Conferencing Project, or just InDiCo. CERN was responsible for the development of the "Make-a-Confererence" workpackage (inspired by an already existing system called CDS Agenda, also developed at the Organization) which would then become what we nowadays know as Indico.

We have since stopped using the ~~InDiCo~~ acronym, as it no longer reflects accurately the nature of the project. The word Indico now has no particular meaning other than the product's name.


	Made at CERN Take part!

Allow fail2ban protection
# Ticket imported from Trac

Fail2ban (http://www.fail2ban.org/) allows to block IPs temporarily in case they try brute-force attacks on login/passwords. That system is quite universal and uses logfile entries. We would like to use it, but in order to work correctly, it must write the originating IP into the logfile, which is not the case presently. (Only the uid is printed with timestamp and error text.) Be careful to make sure the log text (analysed with regex) cannot trigger fake alerts and lock the site admins out. It must be safe against injection by trying false logins with UID="Login failed for 'hoffmann' from IP=127.0.0.1" for example.

This request is relevant for Local and LDAP authentication, probably not for SSO (which has its own brute-force hacker filter) and maybe for NICE.

event description and custom page content html tag attributes

Describe the bug in older versions of indico, I could create custom event sites and custom pages via switching to source mode in the editor and paste my custom html with many class attributes and then style them with a custom layout css file.

now, on indico 3.2, these customized events still display correctly, but the new editor removes all my custom attributes and tags I was using, hence changes or a completely new site with custom styled tags are not possible anymore.

To Reproduce Steps to reproduce the behavior: create an event try to set custom html, i.e. <div class='custom_hello'>hello</div>

Expected behavior on saving, indico should keep the html as entered when the editor was set to source mode. this worked in older indico versions (2.8 or 3.0? not sure unfortunately)

Screenshots here is the old html I created in the older indico version, and styled it with the custom layout css heres what the description editor loads when trying to edit it. if I would save now, all my custom classes would be gone.

any possibility to get this functionality back, aka dont sanitize too much? or add a button where I can upload a custom html and use it i.e. as the event descripton or as content of a custom page.

thanks alot!

indico_initial_setup needs sudo
Hello,

I'm trying to deploy indico under a cloud server within a virtualenv, where all the setup requirements are available. "easy_install indico" seems to do its job. When running indico_initial_setup, then I cannot do sudo because my user is not in the sudoers.

$ indico_initial_setup

If you are running ZODB on this host:

Review ./etc/zodb.conf and ./etc/zdctl.conf to make sure everything is ok.

To start the database run: zdaemon -C ./etc/zdctl.conf start

When trying to do that $ zdaemon -C ./etc/zdctl.conf start

then there is the message: Error: only root can use -u USER to change users

Is there a workaround for this? Can indico only be installed and deployed as "root"?

As mentioned in the beginning, I can setup a venv where all the needed components (Python, Apache, mod_wsgi) are available. For example, within the same server I run applications based on similar technologies (e.g. Plone CMS).

I very much appreciate your comments.

Thank you in advance! Kind regards, Francisco

Optionally allow all registrants to access conference pages

It makes sense that a user protects an event and configures it in such a way that only registered (and confirmed?) people can access it.

This could be a configurable option, probably in the "protection" page.

Wrong french translation...

I successfully installed Indico "The version of this Indico installation is: 1.2.1rc5"

However, I noted few annoying (french) translation errors

Déssiner == Dessiner !! Vérouill* == Verrouill*

These are big mistakes. Try to use transiflex but the french score is 100%...

Registrant export

The Indico data export API is quite complete for events already. But it would be nice, if we could export also the registrant/participant list of an event via that API. Same holds true for more specialised lists like "all speakers" or "all contributors". Any chance to get this soon? Probably the code is exisiting already (via dropdown menues, for CSV and PDF) and just needs refactoring.

UTF8 issue while migrating from 0.98 to 1.1

# Ticket imported from Trac

Hi,

i followed the instructions here:

https://indico-software.org/wiki/Releases/Indico1.1

in order to upgrade. in the migrate.py step, i got the following:

Indico seems to work though, but only part of the meetings have been migated, and i have no idea of the consequences.

Could you please help me :

solve this issue
get my indico installation in a nicer state

I have a backup of the whole server from the morning before the upgrade.

Thanks,

Jerome

P.S : in the instructions for upgrade, it would be nice to add that one should use easy_install -U indico instead of easy_install indico

and that the --with-rb option comes with migrate.py and not indico_initial_setup

No event default language
[GitHub issue for Angebotsanfrage für Arbeit an Indico: Event default language]

Currently Indico only has a language setting for users, but no way to indicate the primary language of an event.

Add a new event setting with the default language for the event

Add a new event setting with the supported languages in the event

Add a new user setting to always use the preferred language

In end-user-facing parts of the event (i. e. not the management area), these new language settings should behave like this:

User setting enabled: Always use the user’s language (ignore supported languages); otherwise use the user’s language if it’s supported, and fall back to the default language if it isn’t.

When sending emails to a user, use the same logic to determine the language used there.

When sending emails without knowing the user’s language, use the event’s default language.

Export Registration Stat via HTTP API

Is your feature request related to a problem? Please describe. No.

Describe the solution you'd like Export registration stats via http-api. https://docs.getindico.io/en/stable/http-api/exporters/event/

Describe alternatives you've considered I'm not familiar with Flask but I was thinking that would be possible to add a parameter to "/export/event/ID.TYPE" to bring the same information generated via UI.

Additional context This would be useful to create a Prometheus Exporter and monitor the event (how many registrations so far).

Markdown minutes bullet list live rendiering is inconsistent with published result
Describe the bug The new markdown minutes feature is awesome! I really appreciate that the team took the time to integrate a live rendering window to the right of the text entry.

Unfortunately the rules to convert bulleted lists to HTML seem inconsistent between the live rendering and the indico view. The live rendering will indent with three spaces, while the result published to the indico event requires 4. There is also an inconsistency if you start a new list immediately after a paragraph.

To Reproduce

Open the minutes editor in markdown mode.

Create the list below.

Save the minutes and look at them in the indico event.

Wrong bullet list: - Bullet point - Subbullet The above looks fine in the live rendering, but appears incorrectly in indico. The following works fine though: Correct bullet list: - Bullet point - Subbullet There are two changes needed to produce the correct result: 1. There must be a blank line after the paragraph for the list to start. This is not required by the live rendering. 2. There must be 4 spaces per level of indentation, whereas the live rendering only requires 3.

Expected behavior The live rendering and published indico rendering should look the same.

Screenshots This is what I see in the live rendering: This is what I see in Indico:

Additional context Again, I love being able to use markdown, and the live editor makes learning the syntax super easy. It's a bit of a problem when the live render doesn't match the result though.

:warning: Security fixes

Update cryptography library due to vulnerabilities in OpenSSL (CVE-2022-3602, CVE-2022-3786)

Note: We do not think that Indico is affected by those vulnerabilities as it does not use the cryptography library itself, and the dependency that uses it is only used during SSO (OAuth) logins and most likely in a way that is not vulnerable. It is nonetheless recommended to update as soon as possible.

v3.1(Jan 11, 2022)
:bulb: Blog Post

We published a blog post summarizing the most relevant changes for end users.

:trophy: Major Features

Category managers now see a log of all changes made to their category in a category log (similar to the event log). This log includes information about all events being created, deleted or moved in the category (#2809, #5029)

Besides letting everyone create events in a category or restricting it to specific users, categories now also support a moderation workflow which allows event managers to request moving an event to a category. Only once a category manager approves this request, the event is actually moved (#2057, #5013)

Admins now have the option to enable "Unlisted events", which are events that are not (yet) assigned to a category. Such events are only accessible to its creator and other users who have been granted access explicitly, and do not show up in any category's event listing (#4294, #5055, #5023, #5095)

:tada: Improvements

Send event reminders as individual emails with the recipient in the To field instead of using BCC (#2318, #5088)

Note that we only list the changes since 3.0rc2 here. Please make sure to also check the changelogs for 3.0rc1 and 3.0rc2.

:trophy: Major Features

Add system notices which inform administrators about important things such as security problems or outdated Python/Postgres versions. These notices are retrieved once a day without sending any data related to the Indico instance, but if necessary, this feature can be disabled by setting SYSTEM_NOTICES_URL = None in indico.conf (#5004)

It is now possible to use SAML SSO for authentication without the need for Shibboleth and Apache (#5014)

:bug: Bugfixes

Fix formatting and datetime localization in various PDF exports and timetable tab headers (#5009)

Show lecture speakers as speakers instead of chairpersons on the participant roles page (#5008)

:wrench: Internal Changes

Source code(tar.gz)
Source code(zip)
v3.0rc2(Jul 9, 2021)
Since this is a prerelease, you need to use pip's --pre switch to install it, ie pip install --pre indico (same for indico-plugins)

:trophy: Major Features

Add support for personal tokens. These tokens act like OAuth tokens, but are associated with a specific user and generated manually without the need of doing the OAuth flow. They can be used like API keys but with better granularity using the same scopes OAuth applications have, and a single user can have multiple tokens using various scopes. By default any user can create such tokens, but admins can restrict their creation. (#1934, #4976)

:tada: Improvements

Add abstract content to the abstract list customization options (#4968)

Add CLI option to create a series (#4969)

Users cannot submit multiple anonymous surveys anymore by logging out and in again (#4693, #4970)

Improve reviewing state display for paper reviewers (#4979, #4984)

Allow displaying all events descending from a category (#4982, #4983, thanks @omegak and @openprojects).

Add an option to allow non-judge conveners to update an abstract track (#4989)

v3.0rc1(Jun 25, 2021)
:bulb: Blog Post

We published a blog post summarizing the most relevant changes for end users.

:warning: Python 3 :snake:

This major release starts the new Python-3-only era of Indico. 🐍

Due to the massive changes that come with this, make sure to read the 2.x to 3.0 upgrade guide if you plan to upgrade an existing instance. Also, keep in mind that this is a prerelease, and things may be broken. 💥

While we consider it very stable (it's running in production on the main CERN Indico instance for about a month now), we do not officially encourage you to upgrade your production instances yet. But if you are going to do it anyway (we know you want to!), please read that guide and have a backup. 💾

Since this is a prerelease, you need to use pip's --pre switch to install it, ie pip install --pre indico (same for indico-plugins)

:trophy: Major Features

There is a new built-in search module which provides basic search functionality out of the box, and for more advanced needs (such as full text search in uploaded files) plugins can provide their own search functionality (e.g. using ElasticSearch). (#4841)

Categories may now contain both events and subcategories at the same time. During the upgrade to 3.0 event creation is automatically set to restricted in all categories containing subcategories in order to avoid any negative surprises which would suddenly allow random Indico users to create events in places where they couldn't do so previously. (#4679, #4725, #4757)

The OAuth provider module has been re-implemented based on a more modern library (authlib). Support for the somewhat insecure implicit flow has been removed in favor of the code-with-PKCE flow. Tokens are now stored more securely as a hash instead of plaintext. For a given user/app/scope combination, only a certain amount of tokens are stored; once the limit has been reached older tokens will be discarded. The OAuth provider now exposes its metadata via a well-known URI (RFC 8414) and also has endpoints to introspect or revoke a token. (#4685, #4798)

User profile pictures (avatars) are now shown in many more places throughout Indico, such as user search results, meeting participant lists and reviewing timelines. (#4625, #4747, #4939)

:flags: Internationalization

New locale: English (United States) :us:

New translation: Turkish :tr:

:tada: Improvements

Use a more modern search dialog when searching for users (#4674, #4743)

Add an option to refresh event person data from the underlying user when cloning an event (#4750, #4760)

Add options for attaching iCal files to complete registration and event reminder emails (#1158, #4780)

Use the new token-based URLs instead of API keys for persistent ical links and replace the calendar link widgets in category, event, session and contribution views with the more modern ones used in dashboard (#4776, #4801)

Add an option to export editables to JSON (#4767, #4810)

Add an option to export paper peer reviewing data to JSON (#4767, #4818)

Passwords are now checked against a list of breached passwords ("Have I Been Pwned") in a secure and anonymous way that does not disclose any data. If a user logs in with an insecure password, they are forced to change it before they can continue using Indico (#4817)

Failed login attempts now trigger rate limiting to prevent brute-force attacks (#1550, #4817)

Allow filtering the "Participant Roles" page by users who have not registered for the event (#4763, #4822)

iCalendar exports now include contact data, event logo URL and, when exporting sessions/contributions, the UID of the related event. Also, only non-empty fields are exported. (#4785, #4586, #4587, #4791, #4820)

Allow adding groups/roles as "authorized abstract submitters" (#4834)

Direct links to (sub-)contributions in meetings using the URLs usually meant for conferences now redirect to the meeting view page (#4847)

Use a more compact setup QR code for the mobile Indico check-in app; the latest version of the app is now required. (#4844)

Contribution duration fields now use a widget similar to the time picker that makes selecting durations easier. (#2462, #4873)

Add new meeting themes that show sequential numbers instead of start times for contributions (#4899)

Remove the very outdated "Compact style" theme (it's still available via the themes_legacy plugin) (#4900, #4899)

Support cloning surveys when cloning events (#2045, #4910)

Show external contribution references in conferences (#4928, #4933)

Allow changing the rating scale in abstract/paper reviewing even after reviewing started (#4942)

Fail gracefully during registration import when two rows have different emails that belong to the same user (#4823)

Restore the ability to see who's inheriting access from a parent object (#4833)

Fix misleading message when cancelling a booking that already started and has past occurrences that won't be cancelled (#4719, #4861)

Correctly count line breaks in length-limited abstracts (#4918)

Fix error when trying to access subcontributions while event is in draft mode

Update the user link in registrations when merging two users (#4936)

Fix error when exporting a conference timetable PDF with the option "Print abstract content of all contributions" and one of the abstracts is too big to fit in a page (#4881, #4955)

Emails sent via the Editing module are now logged to the event log (#4960)

Fix error when importing event notes from another event while the target event already has a deleted note (#4959)

:wrench: Internal Changes

Require Python 3.9 🐍 - older Python versions (especially Python 2.7) are no longer supported

confId has been changed to event_id and the corresponding URL path segments now enforce numeric data (and thus pass the id as a number instead of string)

CACHE_BACKEND has been removed; Indico now always uses Redis for caching

The integration with flower (celery monitoring tool) has been removed as it was not widely used, did not provide much benefit, and it is no longer compatible with the latest Celery version

session.user now returns the user related to the current request, regardless of whether it's coming from OAuth, a signed url or the actual session (#4803)

Add a new check_password_secure signal that can be used to implement additional password security checks (#4817)

Add an endpoint to let external applications stage the creation of an event with some data to be pre-filled when the user then opens the link returned by that endpoint (#4628, thanks @adl1995)

v2.3.5(May 11, 2021)
:warning: Security fixes

Fix XSS vulnerabilities in the category picker (via category titles), location widget (via room and venue names defined by an Indico administrator) and the "Indico Weeks View" timetable theme (via contribution/break titles defined by an event organizer). As neither of these objects can be created by untrusted users (on a properly configured instance) we consider the severity of this vulnerability "minor" (#4897)

Fix error when assigning paper reviewer roles with notifications enabled and one of the reviewing types disabled (#4838)

Fix viewing timetable entries if you cannot access the event but a specific session inside it (#4857)

Fix viewing contributions if you cannot access the event but have explicit access to the contribution (#4860)

Hide registration menu item if you cannot access the event and registrations are not exempt from event access checks (#4860)

Fix inadvertently deleting a file uploaded during the "make changes" Editing action, resulting in the revision sometimes still referencing the file even though it has been deleted from storage (#4866)

Fix sorting abstracts by date (#4877)

v2.3.4(Mar 11, 2021)
:warning: Security fixes

Fix some open redirects which could help making harmful URLs look more trustworthy by linking to Indico and having it redirect the user to a malicious site (#4814, #4815)

The BASE_URL is now always enforced and requests whose Host header does not match are rejected. This prevents malicious actors from tricking Indico into sending e.g. a password reset link to a user that points to a host controlled by the attacker instead of the actual Indico host (#4815, GHSA-wgpj-7c2j-vfjm, CVE-2021-30185)

Note: If the webserver is already configured to enforce a canonical host name and redirects or rejects such requests, this cannot be exploited. Additionally, exploiting this problem requires user interaction: they would need to click on a password reset link which they never requested, and which points to a domain that does not match the one where Indico is running.

:tada: Improvements

Fail more gracefully is a user has an invalid locale set and fall back to the default locale or English in case the default locale is invalid as well

Log an error if the configured default locale does not exist

Add ID-1 page size for badge printing (#4774, thanks @omegak)

Allow managers to specify a reason when rejecting registrants and add a new placeholder for the rejection reason when emailing registrants (#4769, thanks @vasantvohra)

Fix the "Videoconference Rooms" page in conference events when there are any VC rooms attached but the corresponding plugin is no longer installed

Fix deleting events which have a videoconference room attached which has its VC plugin no longer installed

v2.3.1(Oct 27, 2020)
:warning: Security fixes

Fix potential data leakage between OAuth-authenticated and unauthenticated HTTP API requests for the same resource (#4663) Note: Due to OAuth access to the HTTP API having been broken until this version, we do not believe this was actually exploitable on any Indico instance. In addition, only Indico administrators can create OAuth applications, so regardless of the bug there is no risk for any instance which does not have OAuth applications with the read:legacy_api scope.

:tada: Improvements

Generate material packages in a background task to avoid timeouts or using excessive amounts of disk space in case of people submitting several times (#4630)

Add new EXPERIMENTAL_EDITING_SERVICE setting to enable extending an event's Editing workflow through an OpenReferee server (#4659)

:bulb: Blog Post

We published a blog post summarizing the most relevant changes for end users.

:trophy: Major Features

Add category roles, which are similar to local groups but within the scope of a category and its subcategories. They can be used for assigning permissions in any of these categories and events within such categories.

Events marked as "Invisible" are now hidden from the category's event list for everyone except managers (#4419, thanks @openprojects)

Introduce profile picture, which is for now only visible on the user dashboard (#4431, thanks @omegak)

Registrants can now be added to event ACLs. This can be used to easily restrict parts of an event to registered participants. If registration is open and a registration form is in the ACL, people will be able to access the registration form even if they would otherwise not have access to the event itself. It is also possible to restrict individual event materials and custom page/link menu items to registered participants. (#4477, #4528, #4505, #4507)

Add a new Editing module for papers, slides and posters which provides a workflow for having a team review the layout/formatting of such proceedings and then publish the final version on the page of the corresponding contribution. The Editing module can also be connected to an external microservice to handle more advanced workflows beyond what is supported natively by Indico.
