{"id":"CVE-2026-70479","summary":"Open WebUI: SSRF into internal services via unvalidated sub-resource requests in the Playwright web loader","details":"Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. 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.","aliases":["GHSA-w2rx-84hp-gg95","PYSEC-2026-3653"],"modified":"2026-08-12T03:51:09.304985629Z","published":"2026-08-04T19:40:12.035Z","database_specific":{"cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70479.json","cna_assigner":"GitHub_M"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-webui/open-webui","events":[{"introduced":"1a97751e376e00a1897bc3679215ae1c7bd8fd42"},{"fixed":"bef63a2ae915571d50d2722a635e8bfa753d7877"},{"fixed":"f9590b8017199e56d5e953657e6498e3cef1d246"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0.9.6"},{"fixed":"0.11.0"}]}}],"versions":["v0.9.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-70479.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"}]}
