GHSA-cw24-x4mj-fw3q: indico (CVE-2026-107397)

Package	Ecosystem	Affected	Fixed in
indico	PyPI	<3.3.13	3.3.13

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Indico versions before 3.3.13 are vulnerable to cross-site scripting in the minutes editor's conflict UI, which is shown when several users edit the same event minutes concurrently. The source does not say what level of access an attacker needs to exploit it. Upgrade to Indico 3.3.13. As a workaround, set CSP_ENABLED to True in indico.conf, and limit minute-editing rights to trustworthy users.
