{"cve":"CVE-2026-45314","nvd":{"published":"2026-05-15T22:16:54.110","modified":"2026-06-17T10:51:54.337","status":"Modified","description":"Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.3, the channel webhook create/update flow accepts arbitrary profile_image_url values, including data:image/svg+xml;base64,... payloads. The profile image endpoint then decodes and serves this SVG as image/svg+xml without sanitization, allowing attacker-controlled script handlers (for example onload) to execute when the profile-image URL is opened in the browser. This vulnerability is fixed in 0.9.3.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-87"],"references":["https://github.com/open-webui/open-webui/security/advisories/GHSA-3856-3vxq-m6fc","https://github.com/open-webui/open-webui/security/advisories/GHSA-3856-3vxq-m6fc"],"products":["openwebui:open_webui"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-45314","score":0.0022,"percentile":0.12529,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3856-3vxq-m6fc","url":"https://osv.dev/vulnerability/GHSA-3856-3vxq-m6fc","summary":"Open WebUI has XSS via SVG in /api/v1/channels/webhooks/{webhook_id}/profile/image","modified":"2026-07-13T16:43:29.833805622Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.3"],"fixed":["0.9.3"]}]},{"id":"PYSEC-2026-2694","url":"https://osv.dev/vulnerability/PYSEC-2026-2694","summary":"Open WebUI has XSS via SVG in /api/v1/channels/webhooks/{webhook_id}/profile/image","modified":"2026-07-13T16:32:54.789415094Z","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).
