CVE-2026-41062

CVE-2026-41062 · WWBN/AVideo has an incomplete fix for a directory traversal bypass via query string in ReceiveImage downloadURL parameters

Esta página presenta datos de fuentes públicas de vulnerabilidades. Consulta el aviso original antes de actualizar.

WWBN AVideo is an open source video platform. In versions 29.0 and below, the directory traversal fix introduced in commit 2375eb5e0 for `objects/aVideoEncoderReceiveImage.json.php` only checks the URL path component (via `parse_url($url, PHP_URL_PATH)`) for `..` sequences. However, the downstream function `try_get_contents_from_local()` in `objects/functionsFile.php` uses `explode('/videos/', $url)` on the **full URL string** including the query string. An attacker can place the `/videos/../../` traversal payload in the query string to bypass the security check and read arbitrary files from the server filesystem. Commit bd11c16ec894698e54e2cdae25026c61ad1ed441 contains an updated fix.
