CVE-2026-41062 Details
Description
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.
A directory traversal vulnerability has been identified in WWBN AVideo versions 29.0 and below. The issue arises in the 'objects/aVideoEncoderReceiveImage.json.php' file, where the traversal fix only inspects the URL path component for '..' sequences. This oversight allows an authenticated user to craft a same-origin '/videos/...' URL in the query string that bypasses the security check. The downstream function 'try_get_contents_from_local()' then exploits this bypass to read arbitrary files from the server filesystem. The vulnerability was introduced in a previous version and persisted through the initial fix, allowing exploitation via the GIF download URL parameter.
The vulnerability has been patched in commit bd11c16ec894698e54e2cdae25026c61ad1ed441. Users should update to the latest version of WWBN AVideo.
