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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L","score":4.6},"cwes":["CWE-20","CWE-352"],"references":["https://github.com/open-webui/open-webui/security/advisories/GHSA-j6w6-986j-2m2m","https://github.com/open-webui/open-webui/security/advisories/GHSA-j6w6-986j-2m2m"],"products":["openwebui:open_webui"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-45317","score":0.00165,"percentile":0.05676,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j6w6-986j-2m2m","url":"https://osv.dev/vulnerability/GHSA-j6w6-986j-2m2m","summary":"Open WebUI Vulnerable to Cross-Site Request Forgery (CSRF) via Image URL Manipulation","modified":"2026-07-13T16:43:19.459436957Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.3"],"fixed":["0.9.3"]}]},{"id":"PYSEC-2026-2738","url":"https://osv.dev/vulnerability/PYSEC-2026-2738","summary":"Open WebUI Vulnerable to Cross-Site Request Forgery (CSRF) via Image URL Manipulation","modified":"2026-07-13T16:32:16.489821424Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.3"],"fixed":["0.9.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
