{"id":"CVE-2026-45317","state":"PUBLISHED","title":"Open WebUI: Cross-Site Request Forgery (CSRF) via Image URL Manipulation","description":"Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.3, an application-wide Cross-Site Request Forgery (CSRF) vulnerability was found Open-WebUl's image uploading functionality. An attacker can set an image URL to a malicious endpoint, allowing them to perform actions on behalf of a victim user. Any authenticated user can exploit this vulnerability, and any user who views the compromised image (e.g., a profile picture) will unknowingly send a GET request to the attacker-controlled URL. This can lead to cookie theft, denial of service (DoS), or other malicious actions. This vulnerability is fixed in 0.9.3.","publishedAt":"2026-05-15T21:29:44.870Z","updatedAt":"2026-05-18T12:47:43.603Z","severity":{"score":4.6,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["open-webui open-webui"],"affected":[{"vendor":"open-webui","product":"open-webui","versions":[{"version":"< 0.9.3","status":"affected"}]}],"references":["https://github.com/open-webui/open-webui/security/advisories/GHSA-j6w6-986j-2m2m"],"weaknesses":["CWE-20","CWE-352"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/45xxx/CVE-2026-45317.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-45317","state":"PUBLISHED","datePublished":"2026-05-15T21:29:44.870Z","dateUpdated":"2026-05-18T12:47:43.603Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-11T20:50:30.539Z"},"containers":{"cna":{"title":"Open WebUI: Cross-Site Request Forgery (CSRF) via Image URL Manipulation","descriptions":[{"lang":"en","value":"Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline.
