      "value": "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."

En las versiones 29.0 e inferiores, una corrección incompleta de SSRF en el proxy LiveLinks de AVideo añade la validación ’isSSRFSafeURL()’ pero deja vulnerabilidades DNS TOCTOU donde la revinculación de DNS entre la validación y la solicitud HTTP real redirige el tráfico a puntos finales internos.
