Indico: Incomplete Server-Side Request Forgery (SSRF) check

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. Prior to 3.3.13, the previous fix for CVE-2026-25738 did not cover an edge case, allowing an event organizer to submit a crafted URL that points to a prohibited local target but is accepted as valid by Indico. The organizer can read data returned by the target through affected Indico features. This issue is fixed in version 3.3.13.
