      "value": "WWBN AVideo is an open source video platform. In versions up to and including 29.0, two endpoints (plugin/AI/receiveAsync.json.php and objects/EpgParser.php) in AVideo call isSSRFSafeURL() to validate user-supplied URLs, then fetch them using bare file_get_contents() without disabling PHP's automatic redirect following. An attacker can supply a URL pointing to a server they control that returns a 302 redirect to an internal/cloud-metadata address (e.g., http://169.254.169.254/latest/meta-data/). Since isSSRFSafeURL() only validates the initial URL, the redirect target bypasses all SSRF protections. Commit 603e7bf77a835584387327e35560262feb075db3 contains an updated fix."

      "value": "WWBN AVideo es una plataforma de video de código abierto. En versiones hasta la 29.0 inclusive, dos puntos finales (plugin/AI/receiveAsync.json.php y objects/EpgParser.php) en AVideo llaman a isSSRFSafeURL() para validar URLs proporcionadas por el usuario, luego las obtienen usando directamente file_get_contents() sin deshabilitar el seguimiento automático de redirecciones de PHP. Un atacante puede proporcionar una URL que apunte a un servidor que controlan y que devuelve una redirección 302 a una dirección interna/de metadatos de la nube (por ejemplo, http://169.254.169.254/latest/meta-data/). Dado que isSSRFSafeURL() solo valida la URL inicial, el objetivo de la redirección elude todas las protecciones SSRF. El commit 603e7bf77a835584387327e35560262feb075db3 contiene una corrección actualizada."
