CVE-2026-33766
Full vulnerability record from the local CVENow database.
Description
WWBN AVideo is an open source video platform. In versions up to and including 26.0, `isSSRFSafeURL()` validates URLs against private/reserved IP ranges before fetching, but `url_get_contents()` follows HTTP redirects without re-validating the redirect target. An attacker can bypass SSRF protection by redirecting from a public URL to an internal target. Commit 8b7e9dad359d5fac69e0cbbb370250e0b284bc12 contains a patch.

"value": "WWBN AVideo es una plataforma de video de código abierto. En versiones hasta la 26.0 inclusive, ’isSSRFSafeURL()’ valida las URL contra rangos de IP privados/reservados antes de la recuperación, pero ’url_get_contents()’ sigue las redirecciones HTTP sin revalidar el objetivo de la redirección. Un atacante puede eludir la protección SSRF redirigiendo desde una URL pública a un objetivo interno. El commit 8b7e9dad359d5fac69e0cbbb370250e0b284bc12 contiene un parche."
