Prior to 0.9.6, Open WebUI patched SVG XSS in user profile images and webhook profile images but forgot to apply the same fix to model profile images. The ModelMeta class has no validate_profile_image_url field validator, and the model image serving endpoint has no MIME allowlist or nosniff header. Any authenticated user with workspace.models permission (enabled by default) can store a data:image/svg+xml;base64,... payload in a model's profile image and achieve full account takeover of anyone who navigates to the image URL. This vulnerability is fixed in 0.9.6.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N","score":7.6},"cwes":["CWE-79","CWE-116","CWE-693"],"references":["https://github.com/open-webui/open-webui/security/advisories/GHSA-v2qm-5wxj-qhj7","https://github.com/open-webui/open-webui/security/advisories/GHSA-v2qm-5wxj-qhj7"],"products":["openwebui:open_webui"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-54013","score":0.003,"percentile":0.22803,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-v2qm-5wxj-qhj7","url":"https://osv.dev/vulnerability/GHSA-v2qm-5wxj-qhj7","summary":"Open WebUI: Stored XSS to Account Takeover via Model Profile Images ","modified":"2026-07-20T21:15:24.540347467Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.6"],"fixed":["0.9.6"]}]},{"id":"PYSEC-2026-2757","url":"https://osv.dev/vulnerability/PYSEC-2026-2757","summary":"Open WebUI: Stored XSS to Account Takeover via Model Profile Images ","modified":"2026-07-13T16:32:24.907683594Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.6"],"fixed":["0.9.6"]}]}],"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).
