SSRF (Server-Side Request Forgery) in wwbn/avideo (CVE-2026-41055)
Summary
SSRF in wwbn/avideo (CVE-2026-41055). Risk of unauthorized operations or information disclosure. Exploitable via Location.
Original description
The description as published by the source.
WWBN AVideo is an open source video platform. In versions 29.0 and below, an incomplete SSRF fix in AVideo's LiveLinks proxy adds isSSRFSafeURL() validation but leaves DNS TOCTOU vulnerabilities where DNS rebinding between validation and the actual HTTP request redirects traffic to internal endpoints. Commit 8d8fc0cadb425835b4861036d589abcea4d78ee8 contains an updated fix.
