CVE-2026-39369 Details
Description
WWBN AVideo is an open source video platform. In versions 26.0 and prior, objects/aVideoEncoderReceiveImage.json.php allowed an authenticated uploader to fetch attacker-controlled same-origin /videos/... URLs, bypass traversal scrubbing, and expose server-local files through the GIF poster storage path. The vulnerable GIF branch could be abused to read local files such as /etc/passwd or application source files and republish those bytes through a normal public GIF media URL.
A local file disclosure vulnerability has been identified in WWBN AVideo versions through 26.0. The issue arises in 'objects/aVideoEncoderReceiveImage.json.php', where an authenticated uploader can exploit the GIF poster storage path to access server-local files. The vulnerability allows bypassing traversal scrubbing to fetch attacker-controlled same-origin '/videos/...' URLs, potentially exposing sensitive files such as '/etc/passwd' or application source files through a public GIF media URL.
It is recommended to reject any remote image URLs that contain traversal markers, disallow attacker-controlled same-origin '/videos/...' fetches from resolving into local file reads, and validate GIF content before saving it to public media storage. Additionally, ensure that invalid-image cleanup checks the correct destination path.
