Seafile SeaDoc converter 2.0.4 before 2.0.11 and 3.0.0 before 3.0.8 contains an absolute path traversal vulnerability that allows unauthenticated attackers holding a public share token to execute code. Attackers supply an absolute filename to /api/v1/confluence-to-wiki/ to extract a ZIP from download_url into the Python library path, then trigger the module's import via a file-convert request.
