Summary
Stonewuu ai-fusion-video through 1.2.0 is affected. A path traversal flaw (CWE-22) in the subDir parameter of the media upload endpoint POST /api/storage/upload does not normalize parent-directory sequences, so uploads are written outside the media directory. An authenticated user can write attacker-controlled files with chosen extensions anywhere the service account can write.

Description from the CNA
Stonewuu ai-fusion-video through 1.2.0 contains a path traversal vulnerability that allows authenticated users to write uploaded files outside the media directory via the subDir parameter of POST /api/storage/upload. Attackers can supply parent-directory sequences that LocalStorageStrategy.storeBytes never normalizes, creating directories and writing attacker-controlled files with chosen extensions anywhere the service account can write.
