Prior to 0.10.0, backend/open_webui/routers/terminals.py built the ws_terminal upstream URL from an unencoded session_id and appended user_id as a query parameter, allowing query injection to make the terminal backend resolve another user identity; the HTTP proxy path also forwarded X-User-Id as an integrity-unbound identity claim. This issue is fixed in version 0.10.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H","score":8.0},"cwes":["CWE-287","CWE-290"],"references":["https://github.com/open-webui/open-webui/commit/5f3a628a8d291bb5d33e1a0b0c89fb62a2927934","https://github.com/open-webui/open-webui/pull/26042","https://github.com/open-webui/open-webui/releases/tag/v0.10.0","https://github.com/open-webui/open-webui/security/advisories/GHSA-j657-m4c4-24jq"],"products":["openwebui:open_webui"],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-59224","score":0.00391,"percentile":0.33226,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j657-m4c4-24jq","url":"https://osv.dev/vulnerability/GHSA-j657-m4c4-24jq","summary":"Open WebUI: Terminal proxy forwards a spoofable, integrity-unbound user identity to the upstream (X-User-Id header and ws_terminal session_id query injection)","modified":"2026-08-04T14:40:42.000213965Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.10.0"],"fixed":["0.10.0"]}]},{"id":"PYSEC-2026-3600","url":"https://osv.dev/vulnerability/PYSEC-2026-3600","summary":"Open WebUI: Terminal proxy forwards a spoofable, integrity-unbound user identity to the upstream (X-User-Id header and ws_terminal session_id query injection)","modified":"2026-08-04T14:30:17.730208552Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.10.0"],"fixed":["0.10.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
