Name of the Vulnerable Software and Affected Versions
Open WebUI versions 0.9.6 through 0.9.9
Description
The
sanitize proxy path function in backend/open webui/routers/terminals.py fails to properly normalize proxy paths by decoding them only eight times. This allows a nine-times percent-encoded ../ traversal value to bypass normalization checks and be decoded by the upstream terminal server, potentially leading to path traversal.Recommendations
Update to version 0.10.0.
