Unauthenticated service interruption via persistent temporary files
Published May 19, 2026 · Updated May 19, 2026
Denial of service in AutoGPT 0.4.2 through 0.6.51 allows remote attackers to exhaust server disk space through repeated agent downloads. The download_agent_file function creates each response with NamedTemporaryFile(delete=False), and FileResponse leaves the resulting file on disk. The public endpoint requires only a valid public listing ID; repeated requests can fill temporary storage until database and backend services fail.
