Prior to 0.9.6, the SafePlaywrightURLLoader implements a validate_url function to prevent SSRF attacks by checking the IP address of the user-provided URL. However, this validation is performed only on the initial URL. Since Playwright automatically follows HTTP redirects (301/302) by default, an attacker can bypass the validation by providing a safe URL that redirects to a restricted internal network address (e.g., localhost, Docker container network, or Cloud Metadata). This allows the application to access internal services despite ENABLE_RAG_LOCAL_WEB_FETCH being set to False This vulnerability is fixed in 0.9.6.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7},"cwes":["CWE-918"],"references":["https://github.com/open-webui/open-webui/security/advisories/GHSA-jrfp-m64g-pcwv","https://github.com/open-webui/open-webui/security/advisories/GHSA-jrfp-m64g-pcwv"],"products":["openwebui:open_webui"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-54018","score":0.00386,"percentile":0.32645,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-jrfp-m64g-pcwv","url":"https://osv.dev/vulnerability/GHSA-jrfp-m64g-pcwv","summary":"Open WebUI: SSRF Protection Bypass in Playwright Web Loader via HTTP Redirects","modified":"2026-07-20T21:15:27.577999925Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.6"],"fixed":["0.9.6"]}]},{"id":"PYSEC-2026-2743","url":"https://osv.dev/vulnerability/PYSEC-2026-2743","summary":"Open WebUI: SSRF Protection Bypass in Playwright Web Loader via HTTP Redirects","modified":"2026-07-13T16:32:21.010135018Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.6"],"fixed":["0.9.6"]}]}],"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).
