SCA: security update for indico (GHSA-jxc4-54g3-j7vp)

medium Tenable Cloud Security Plugin ID 437771

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for
Flask. Versions prior to 3.3.10 are vulnerable to cross-site scripting when uploading certain file types
as materials. Users should upgrade to version 3.3.10 to receive a patch. To apply the fix itself updating
is sufficient, but to benefit from the strict Content Security Policy (CSP) Indico now applies by default
for file downloads, update the webserver config in case one uses nginx with Indico's `STATIC_FILE_METHOD`
set to `xaccelredirect`. For further directions, consult the GitHub Security advisory or Indico setup
documentation. Some workarounds are available. Use the webserver config to apply a strict CSP for material
download endpoints, and/or only let trustworthy users create content (including material uploads, which
speakers can typically do as well) on Indico. (CVE-2026-25739)
