DescriptionIndico 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.
