CVE-2025-58161: MobSF Path Traversal in GET /download/<filename> using absolute filenames
(updated )
The GET /download/ route uses string path verification via os.path.commonprefix, which allows an authenticated user to download files outside the DWD_DIR download directory from “neighboring” directories whose absolute paths begin with the same prefix as DWD_DIR (e.g., …/downloads_bak, …/downloads.old). This is a Directory Traversal (escape) leading to a data leak.
