CVE-2026-41055

high

Description

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.
