Summary

Indico versions before 3.3.13 are affected. Improper neutralization of input (CWE-79) lets a user who can create content, such as a speaker who can create minutes, store crafted HTML in event minutes. When two users edit the same minutes concurrently, the minute editor conflict view runs the attacker's script in the viewer's browser within the Indico origin. Exploitation requires low privileges and user interaction by the victim.

Description from the CNA

Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. Prior to 3.3.13, users who can create content, including speakers who can create minutes, can store crafted HTML in event minutes. When concurrent edits are made to the same minutes, the minute editor conflict UI can execute attacker-controlled script in the viewer's browser in the Indico origin. This issue is fixed in version 3.3.13.
