{"id":"CVE-2026-54018","state":"PUBLISHED","title":"Open WebUI: SSRF Protection Bypass in Playwright Web Loader via HTTP Redirects","description":"Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. 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.","publishedAt":"2026-06-23T16:42:00.074Z","updatedAt":"2026-06-23T17:56:11.400Z","severity":{"score":7.7,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["open-webui open-webui"],"affected":[{"vendor":"open-webui","product":"open-webui","versions":[{"version":"< 0.9.6","status":"affected"}]}],"references":["https://github.com/open-webui/open-webui/security/advisories/GHSA-jrfp-m64g-pcwv"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54018.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54018","state":"PUBLISHED","datePublished":"2026-06-23T16:42:00.074Z","dateUpdated":"2026-06-23T17:56:11.400Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-11T16:34:11.636Z"},"containers":{"cna":{"title":"Open WebUI: SSRF Protection Bypass in Playwright Web Loader via HTTP Redirects","descriptions":[{"lang":"en","value":"Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline.
