Arbitrary file read via poisoned path metadata
Published Sep 5, 2026 · Updated Sep 7, 2026
Path traversal in JoomUnited WP File Download 6.3.8 and earlier allows remote authenticated users to read server files via remoteurl. The unprotected file.save handler stores remoteurl in _wpfd_file_metadata['file'], and the init-hooked streaming endpoint resolves and returns that path without authentication. Subscriber-level access is required to poison the metadata, after which any caller can retrieve files readable by the WordPress process.
