Technical details
A path traversal vulnerability exists in the `extract_media` function within `gateway/platforms/base.py`. The component uses a regular expression to identify `MEDIA:` tags in LLM responses but fails to perform directory containment or traversal checks on the resulting file paths. By using prompt injection, a remote attacker can force the agent to output a path like `MEDIA:/var/backups/data.zip`. The system then uses `os.path.expanduser()` and reads the file from the host filesystem to send as an attachment. While the exploit is restricted to files with specific extensions (e.g., .csv, .txt, .pdf, .zip, .docx), it bypasses the sandbox restrictions enforced in other modules like `file_tools.py`. As of the advisory date, the vendor has not responded to disclosure attempts.
