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 a server-side request forgery flaw, because an earlier fix missed an edge case that let a crafted URL pointing at a local target pass validation. An attacker who can supply such a URL, which per the source typically means an event organizer, can make Indico send requests to internal targets such as localhost or cloud metadata endpoints. Upgrade to Indico 3.3.13. Setting the http_proxy and https_proxy environment variables to route outgoing requests through a restricting proxy is an optional extra measure.
