Authenticated file read via query-string path traversal
Published Apr 21, 2026 · Updated Apr 21, 2026
Path traversal in AVideo 29.0 and earlier allows remote authenticated users to read server files through crafted ReceiveImage requests. ReceiveImage validates only the parsed URL path, but try_get_contents_from_local splits the entire URL at /videos/ and resolves query-string traversal outside the videos directory. Upload permission and an owned video are required; image files can be retrieved through the thumbnail URL, while other files expose existence and size and are deleted after a race window.
