Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Indico versions before 3.3.10 are vulnerable to server-side request forgery in several places, where user-supplied URLs can make Indico send requests to internal or special targets such as localhost or cloud metadata endpoints. An attacker who can reach these features, with event organizer access needed to see returned data, could use them to probe internal services. Upgrade to Indico 3.3.10 or later. Until then, the advisory suggests routing outgoing requests through a proxy via the http_proxy and https_proxy environment variables, set for both the uwsgi and celery services.
