      "value": "WWBN AVideo is an open source video platform. Versions prior to 29.0 contain an unauthenticated Reflected XSS vulnerability through AVideo YouTubeAPI Gallery Pagination. The $_GET['search'] query parameter is concatenated directly into the href attribute of two pagination links in plugin/YouTubeAPI/gallerySection.php (lines 67 and 74) with no htmlspecialchars, no urlencode, and no allow-list check. An injected <script> element is then extracted by the AVideo Layout plugin and concatenated into a single trailing inline script block at the bottom of the page, where the browser executes it.  Any unauthenticated attacker can lure a victim into following a crafted URL to execute arbitrary JavaScript under the AVideo origin, which can read non-HttpOnly cookies and issue authenticated AJAX requests as the victim, and when the victim is an administrator, it can perform any cookie-authenticated admin action (create user, promote to admin, change configuration, install plugin), escalating a single click into full administrative takeover. This issue has been patched by this commit: https://github.com/WWBN/AVideo/commit/f50fc033b7adb36f1ffd6640e7826468bdafdec3."

      "value": "WWBN AVideo es una plataforma de video de código abierto. Las versiones anteriores a la 29.0 contienen una vulnerabilidad de XSS Reflejado no autenticado a través de la paginación de la galería AVideo YouTubeAPI. El parámetro de consulta parámetro ’search’ se concatena directamente en el atributo href de dos enlaces de paginación en plugin/YouTubeAPI/gallerySection.php (líneas 67 y 74) sin htmlspecialchars, sin urlencode y sin verificación de lista de permitidos. Un elemento [script_tag] inyectado es luego extraído por el plugin AVideo Layout y concatenado en un único bloque de script en línea al final de la página, donde el navegador lo ejecuta. Cualquier atacante no autenticado puede atraer a una víctima para que siga una URL manipulada para ejecutar JavaScript arbitrario bajo el origen de AVideo, lo que puede leer cookies no HttpOnly y emitir solicitudes AJAX autenticadas como la víctima, y cuando la víctima es un administrador, puede realizar cualquier acción de administrador autenticada por cookie (crear usuario, promover a administrador, cambiar configuración, instalar plugin), escalando un solo clic a una toma de control administrativa completa. Este problema ha sido parcheado por este commit: https://github.com/WWBN/AVideo/commit/f50fc033b7adb36f1ffd6640e7826468bdafdec3."
