Path traversal in AVideo - CVE-2026-41062
Published: November 11, 2026
Vulnerability details
The vulnerability allows a remote user to disclose server-readable images and reveal other files' existence and size, with possible disclosure during a deletion race.
The vulnerability exists due to path traversal in AVideo's ReceiveImage endpoint when validation checks only URL paths but try_get_contents_from_local() derives filesystem paths from full URLs. A remote user can use upload permission and an owned video's identifier to submit downloadURL_image=http://avideo.example.com/x?a=/videos/../../../../../../etc/passwd or equivalent downloadURL_* parameters, bypassing validation to access files outside the intended directory.
