CVE-2025-47909

CSRF via scheme-blind TrustedOrigins matching

Published Aug 29, 2025 · Updated Aug 29, 2025

CSRF in TrustedOrigins in Gorilla Web Toolkit gorilla/csrf allows man-in-the-middle attackers to submit cross-origin requests. The Origin check compares a parsed request's host against TrustedOrigins without requiring its scheme to match the trusted HTTPS origin. Exploitation requires an HTTPS application configured with TrustedOrigins and a network position that can inject an HTTP form; accepted requests can perform application-defined actions with the victim's session.
