Changelog

Version 3.3

Unreleased

Major Features

  • Nothing so far

Internationalization

  • Nothing so far

Improvements

Bugfixes

  • Prevent room booking sidebar menu from overlapping with the user dropdown menu (:pr:`5910`)

Internal Changes

  • Use (dart-)sass instead of the deprecated node-sass/libsass for CSS compilation (:pr:`5734`)
  • Add event.is_field_data_locked signal, allowing plugins to lock registration form fields on a per-registration basis (:pr:`5424`)

Version 3.2.8

Unreleased

Improvements

  • None so far :(

Bugfixes

Internal Changes

  • None so far

Version 3.2.7

Released on August 02, 2023

Bugfixes

  • Fix not being able to remove the last entry from a room ACL (:pr:`5863`, thanks :user:`SegiNyn`)
  • Fix conditional fields remaining hidden in abstract judgment form (:pr:`5873`)

Version 3.2.6

Released on July 20, 2023

Security fixes

  • Fix an XSS vulnerability in various confirmation prompts commonly used when deleting things. Exploitation requires someone with at least submission privileges (such as a speaker) and then rely on someone else to attempt to delete this content. However, considering that event organizers may indeed delete suspicious-looking content when encountering it, there is a non-negligible risk of such an attack to succeed. Because of this it is strongly recommended to upgrade as soon as possible (:pr:`5862`, :cve:`CVE-2023-37901`)

Internationalization

  • New translation: Czech

Improvements

  • Show which files were added or modified on each editing timeline revision (:pr:`5802`)
  • Support rendering Japanese, Chinese & Korean letters in PDFs (:issue:`3120`, :pr:`5842`, thanks :user:`adamjenkins`)
  • Add button to adapt columns widths on the reviewing area's abstracts list (:pr:`5837`)
  • Allow cloning category-level badge/poster templates into another category (:pr:`5775`, thanks :user:`SegiNyn`)
  • Allow using a custom link text in the {event_link} email placeholder, using the {event_link:something-else-here} syntax (:issue:`5858`, :pr:`5860`)
  • Add option to add "event cancelled" semantics for event labels, which will disable reminders for events having this label (:issue:`5285`, :pr:`5861`)

Bugfixes

  • Use correct name formatting in person link fields (:pr:`5835`)

Internal Changes

  • Support Python 3.11

Version 3.2.5

Released on June 26, 2023

Security fixes

  • Fix an XSS vulnerability in the LaTeX \href macro when rendering it client-side. Previously, it was possible to embed arbitrary JavaScript there using the javascript: protocol. The underlying MathJax library has now been updated to version 3 which allows blacklisting certain protocols, thus allowing only http, https and mailto links in \href macros (:pr:`5818`)

Improvements

  • Show actual recipient data in the email preview instead of the that of the event creator (:pr:`5794`)
  • Add an option to set a maximum number of choices in a multi-choice field (:pr:`5800`)

Version 3.2.4

Released on May 26, 2023

Version 3.2.3

Released on February 23, 2023

Security fixes

Note

The risk of malicious HTML (e.g. scripts) in the global announcement is minimal as only Indico administrators can set such an announcement anyway. However, in the unlikely case that an administrator becomes malicious or is compromised, they would have been be able to perform XSS against their Indico instance.

Internal Changes

  • Refactor email-sending dialog using React (:pr:`5547`)

Version 3.2.1

Released on November 10, 2022

Security fixes

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.

Internationalization

Improvements

Bugfixes

  • Fix meeting minutes being shown when they are expected to be hidden (:pr:`5475`)

  • Refactor service request email generation so plugins can override sender and reply-to addresses for these emails (:pr:`5501`)
  • Deleting a session no longer leaves orphaned session blocks (:pr:`5533`, thanks :user:`omegak`)
  • Indicate in the registration_deleted signal whether it's a permanent deletion from the database or just a soft-deletion (:pr:`5559`)

Internal Changes

Version 3.1

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 (:issue:`2809`, :pr:`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 (:issue:`2057`, :pr:`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 (:issue:`4294`, :issue:`5055`, :pr:`5023`, :pr:`5095`)

Internal Changes

Version 3.0

Released on July 16, 2021

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 :data:`SYSTEM_NOTICES_URL` to None in indico.conf (:pr:`5004`)
  • It is now possible to use :ref:`SAML SSO <saml>` for authentication without the need for Shibboleth and Apache (:pr:`5014`)

Bugfixes

  • Fix formatting and datetime localization in various PDF exports and timetable tab headers (:pr:`5009`)
  • Show lecture speakers as speakers instead of chairpersons on the participant roles page (:pr:`5008`)

  • Add category.extra_events signal (:pr:`5005`, thanks :user:`omegak`)

Version 3.0rc2

Released on July 09, 2021

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. (:issue:`1934`, :pr:`4976`)

Improvements

Bugfixes

Version 3.0rc1

Released on June 25, 2021

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). (:pr:`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. (:issue:`4679`, :pr:`4725`, :pr:`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. (:issue:`4685`, :pr:`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. (:issue:`4625`, :pr:`4747`, :pr:`4939`)

Internationalization

  • New locale: English (United States)
  • New translation: Turkish

Improvements

  • Use a more modern search dialog when searching for users (:issue:`4674`, :pr:`4743`)
  • Add an option to refresh event person data from the underlying user when cloning an event (:issue:`4750`, :pr:`4760`)
  • Add options for attaching iCal files to complete registration and event reminder emails (:issue:`1158`, :pr:`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 (:issue:`4776`, :pr:`4801`)
  • Add an option to export editables to JSON (:issue:`4767`, :pr:`4810`)
  • Add an option to export paper peer reviewing data to JSON (:issue:`4767`, :pr:`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 (:pr:`4817`)

  • Allow filtering the "Participant Roles" page by users who have not registered for the event (:issue:`4763`, :pr:`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. (:issue:`4785`, :issue:`4586`, :issue:`4587`, :issue:`4791`, :pr:`4820`)
  • Allow adding groups/roles as "authorized abstract submitters" (:pr:`4834`)
  • Direct links to (sub-)contributions in meetings using the URLs usually meant for conferences now redirect to the meeting view page (:pr:`4847`)
  • Use a more compact setup QR code for the mobile Indico check-in app; the latest version of the app is now required. (:pr:`4844`)
  • Contribution duration fields now use a widget similar to the time picker that makes selecting durations easier. (:issue:`2462`, :pr:`4873`)

  • Correctly count line breaks in length-limited abstracts (:pr:`4918`)
  • Fix error when trying to access subcontributions while event is in draft mode
  • Update the user link in registrations when merging two users (:pr:`4936`)

  • Emails sent via the Editing module are now logged to the event log (:pr:`4960`)
  • Fix error when importing event notes from another event while the target event already has a deleted note (:pr:`4959`)

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)

Version 2.3.6

Unreleased

Bugfixes

  • None so far :)

Version 2.3.5

Released on May 11, 2021

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" (:pr:`4897`)

Internationalization

  • New translation: Polish
  • New translation: Mongolian

Improvements

  • Add an option to not disclose the names of editors and commenters to submitters in the Paper Editing module (:issue:`4829`, :pr:`4865`)

Bugfixes

  • Do not show soft-deleted long-lasting events in category calendar (:pr:`4824`)
  • Do not show management-related links in editing hybrid view unless the user has access to them (:pr:`4830`)
  • Fix error when assigning paper reviewer roles with notifications enabled and one of the reviewing types disabled (:pr:`4838`)
  • Fix viewing timetable entries if you cannot access the event but a specific session inside it (:pr:`4857`)
  • Fix viewing contributions if you cannot access the event but have explicit access to the contribution (:pr:`4860`)
  • Hide registration menu item if you cannot access the event and registrations are not exempt from event access checks (:pr:`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 (:pr:`4866`)
  • Fix sorting abstracts by date (:pr:`4877`)

Internal Changes

Version 2.3.4

Released on March 11, 2021

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 (:issue:`4814`, :pr:`4815`)
  • The :data:`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 (:pr:`4815`)

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.

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 (:pr:`4774`, thanks :user:`omegak`)
  • Allow managers to specify a reason when rejecting registrants and add a new placeholder for the rejection reason when emailing registrants (:pr:`4769`, thanks :user:`vasantvohra`)

Bugfixes

  • 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
  • Do not auto-redirect to SSO when an MS office user agent is detected (:issue:`4720`, :pr:`4731`)
  • Allow Editing team to view editables of unpublished contributions (:issue:`4811`, :pr:`4812`)

Internal Changes

  • Also trigger the ical-export metadata signal when exporting events for a whole category
  • Add primary_email_changed signal (:pr:`4802`, thanks :user:`openprojects`)

Version 2.3.3

Released on January 25, 2021

Security fixes

  • JSON locale data for invalid locales is no longer cached on disk; instead a 404 error is triggered. This avoids creating small files in the cache folder for each invalid locale that is requested. (:pr:`4766`)

Internationalization

  • New translation: Ukrainian

Improvements

  • Add a new "Until approved" option for a registration form's "Modification allowed" setting (:pr:`4740`, thanks :user:`vasantvohra`)

Bugfixes

  • Fix error when converting malformed HTML links to LaTeX
  • Hide inactive contribution/abstract fields in submit/edit forms (:pr:`4755`)
  • Fix adding registrants to a session ACL

Internal Changes

  • Videoconference plugins may now display a custom message for the prompt when deleting a videoconference room (:pr:`4733`)
  • Videoconference plugins may now override the behavior when cloning an event with attached videoconference rooms (:pr:`4732`)

Version 2.3.2

Released on November 30, 2020

Improvements

Bugfixes

  • Only consider actual speakers in the "has registered speakers" contribution list filter (:pr:`4712`, thanks :user:`bpedersen2`)
  • Correctly filter events in "Sync with your calendar" links (this fix only applies to newly generated links) (:pr:`4717`)
  • Correctly grant access to attachments inside public sessions/contribs even if the event is more restricted (:pr:`4721`)
  • Fix missing filename pattern check when suggesting files from Paper Peer Reviewing to submit for Editing (:pr:`4715`)
  • Fix filename pattern check in Editing when a filename contains dots (:pr:`4715`)
  • Require explicit admin override (or being whitelisted) to override blockings (:pr:`4706`)
  • Clone custom abstract/contribution fields when cloning abstract settings (:pr:`4724`, thanks :user:`bpedersen2`)
  • Fix error when rescheduling a survey that already has submissions (:issue:`4730`)

Version 2.3.1

Released on October 27, 2020

Security fixes

  • Fix potential data leakage between OAuth-authenticated and unauthenticated HTTP API requests for the same resource (:pr:`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.

Improvements

Bugfixes

  • Only show the warning about draft mode in a conference if it actually has any contributions or timetable entries
  • Do not show incorrect modification deadline in abstract management area if no such deadline has been set (:pr:`4650`)

  • Fix paper revision submission field being displayed for judges/reviewers (:pr:`4667`)
  • Fix managers not being able to submit paper revisions on behalf of the user (:pr:`4667`)

Internal Changes

  • Add registration_form_wtform_created signal and send form data in registration_created and registration_updated signals (:pr:`4642`, thanks :user:`omegak`)
  • Add logged_in signal

Version 2.3

Released on September 14, 2020

Note

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

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 (:issue:`4419`, thanks :user:`openprojects`)
  • Introduce profile picture, which is for now only visible on the user dashboard (:issue:`4431`, thanks :user:`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. (:issue:`4477`, :issue:`4528`, :issue:`4505`, :issue:`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.
