From 0.9.6 until 0.11.0, with WEB_LOADER_ENGINE=playwright, the Playwright web loader validates only the top-level page request and lets sub-resource requests pass unvalidated. A page supplied by an authenticated user can use JavaScript to reach blocked internal addresses, and returned DOM can include data read from those addresses in web-search or RAG output. This issue is fixed in 0.11.0.","published":"2026-08-04T19:40:12.035Z","modified":"2026-09-10T03:30:58.672086149Z","cvss":{"score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"open-webui","fixedVersion":"0.11.0"}],"fix":{"url":"https://github.com/open-webui/open-webui/commit/bef63a2ae915571d50d2722a635e8bfa753d7877","label":"open-webui/open-webui@bef63a2"},"references":[{"type":"WEB","url":"https://github.com/open-webui/open-webui/releases/tag/v0.11.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70479.json"},{"type":"ADVISORY","url":"https://github.com/open-webui/open-webui/security/advisories/GHSA-w2rx-84hp-gg95"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70479"},{"type":"FIX","url":"https://github.com/open-webui/open-webui/commit/bef63a2ae915571d50d2722a635e8bfa753d7877"},{"type":"FIX","url":"https://github.com/open-webui/open-webui/pull/27526"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:30:58.672086149Z"}}
