{"cve":"CVE-2026-54008","nvd":{"published":"2026-06-23T18:18:05.927","modified":"2026-06-25T13:35:46.923","status":"Analyzed","description":"Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.6, backend/open_webui/utils/oauth.py::_process_picture_url calls validate_url(picture_url) on the initial URL only, then invokes aiohttp.ClientSession.get(picture_url, ...) without allow_redirects=False. aiohttp's default is allow_redirects=True, max_redirects=10; the function does not pass the project's AIOHTTP_CLIENT_ALLOW_REDIRECTS env constant either. An attacker with a valid OAuth IdP identity can therefore submit a public URL that 302-redirects to an internal address and read the internal response body via the attacker's own profile_image_url field. 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:N/S:C/C:H/I:L/A:N","score":8.5},"cwes":["CWE-918"],"references":["https://github.com/open-webui/open-webui/security/advisories/GHSA-226f-f24g-524w","https://github.com/open-webui/open-webui/security/advisories/GHSA-226f-f24g-524w"],"products":["openwebui:open_webui"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-54008","score":0.00326,"percentile":0.25689,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-226f-f24g-524w","url":"https://osv.dev/vulnerability/GHSA-226f-f24g-524w","summary":"Open WebUI: Redirect-Bypass SSRF in OAuth `_process_picture_url` (incomplete-fix sibling of CVE-2026-45401)","modified":"2026-07-13T16:42:55.257503767Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.6"],"fixed":["0.9.6"]}]},{"id":"PYSEC-2026-2690","url":"https://osv.dev/vulnerability/PYSEC-2026-2690","summary":"Open WebUI: Redirect-Bypass SSRF in OAuth `_process_picture_url` (incomplete-fix sibling of CVE-2026-45401)","modified":"2026-07-13T16:32:54.597055250Z","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).
