Last modified Jun 17, 2026

CVE-2026-41055 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
