CVE-2026-41055 Details
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.
A server-side request forgery (SSRF) vulnerability has been identified in the LiveLinks proxy of WWBN AVideo, an open-source video platform. This issue affects versions through 29.0. The vulnerability arises from an incomplete fix that introduces validation for redirect URLs but fails to address timing-of-check-to-use vulnerabilities. These allow DNS rebinding attacks to redirect internal traffic through the server, potentially exposing sensitive endpoints such as cloud metadata services.
Users are advised to update to version 29.0 or later, where this vulnerability has been addressed.
