{"id":"CVE-2026-45317","summary":"Open WebUI: Cross-Site Request Forgery (CSRF) via Image URL Manipulation","details":"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.","aliases":["GHSA-j6w6-986j-2m2m","PYSEC-2026-2738"],"modified":"2026-07-15T01:49:16.701111892Z","published":"2026-05-15T21:29:44.870Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-20","CWE-352"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45317.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45317.json"},{"type":"ADVISORY","url":"https://github.com/open-webui/open-webui/security/advisories/GHSA-j6w6-986j-2m2m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45317"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-webui/open-webui","events":[{"introduced":"0"},{"fixed":"adc9076d176679fd913c5dc44d0bd4d8f86d1fc3"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.9.3"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:openwebui:open_webui:*:*:*:*:*:*:*:*"}}],"versions":["v0.9.2","v0.9.1","v0.9.0","v0.8.12","v0.8.11","v0.8.10","v0.8.9","v0.8.8","v0.8.7","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.2","v0.7.1","v0.7.0","v0.6.43","v0.6.42","v0.6.41","v0.6.40","v0.6.39","v0.6.38","v0.6.37","v0.6.36","v0.6.34","v0.6.35","v0.6.33","v0.6.32","v0.6.31","v0.6.30","v0.6.29","v0.6.28","v0.6.27","v0.6.26","v0.6.25","v0.6.24","v0.6.23","v0.6.22","v0.6.21","v0.6.20","v0.6.19","v0.6.18","v0.6.17","v0.6.16","v0.6.15","v0.6.14","v0.6.13","v0.6.12","v0.6.11","v0.6.10","v0.6.9","v0.6.8","v0.6.7","v0.6.6","v0.6.5","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.16","v0.5.20","v0.5.19","v0.5.18","v0.5.17","v0.5.15","v0.5.14","v0.5.12","v0.5.13","v0.5.11","v0.5.10","v0.5.9","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.35","v0.3.34","v0.3.33","v0.3.32","v0.3.31","v0.3.30","v0.3.29","v0.3.28","v0.3.27","v0.3.26","v0.3.25","v0.3.24","v0.3.23","v0.3.22","v0.3.21","v0.3.20","v0.3.19","v0.3.18","v0.3.17","v0.3.16","v0.3.15","v0.3.14","v0.3.13","v0.3.12","v0.3.11","v0.3.10","v0.3.9","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.125","v0.1.124","v0.1.123","v0.1.122","v0.1.114","v0.1.121","v0.1.120","v0.1.119","v0.1.118","v0.1.117","v0.1.116","v0.1.115","v0.1.108","v0.1.113","v0.1.112","v0.1.111","v0.1.110","v0.1.109","v0.1.107","v0.1.106","v0.1.105","v0.1.104","v0.1.103","v0.1.102"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45317.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L"}]}
