Versions 4.7.0 and below are vulnerable to an unauthenticated, full-read SSRF vulnerability. The ZITADEL Login UI (V2) treats the x-zitadel-forward-host header as a trusted fallback for all deployments, including self-hosted instances. This allows an unauthenticated attacker to force the server to make HTTP requests to arbitrary domains, such as internal addresses, and read the responses, enabling data exfiltration and bypassing network-segmentation controls. This issue is fixed in version 4.7.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":8.6},"cwes":["CWE-918"],"references":["https://github.com/zitadel/zitadel/commit/4c879b47334e01d4fcab921ac1b44eda39acdb96","https://github.com/zitadel/zitadel/security/advisories/GHSA-7wfc-4796-gmg5"],"products":["zitadel:zitadel"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-67494","score":0.00444,"percentile":0.38312,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7wfc-4796-gmg5","url":"https://osv.dev/vulnerability/GHSA-7wfc-4796-gmg5","summary":"ZITADEL Vulnerable to Unauthenticated Full-Read SSRF via V2 Login","modified":"2025-12-15T20:25:57.450163Z","packages":[{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":["<1.80.0-v2.20.0.20251208091519-4c879b47334e"],"fixed":["1.80.0-v2.20.0.20251208091519-4c879b47334e"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=1.83.4 <=1.87.5"],"fixed":[]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=4.0.0-rc.1 <4.7.1"],"fixed":["4.7.1"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel/v2","purl":"pkg:golang/github.com/zitadel/zitadel/v2","ranges":["<1.80.0-v2.20.0.20251208091519-4c879b47334e"],"fixed":["1.80.0-v2.20.0.20251208091519-4c879b47334e"]}]},{"id":"GO-2025-4210","url":"https://osv.dev/vulnerability/GO-2025-4210","summary":"ZITADEL Vulnerable to Unauthenticated Full-Read SSRF via V2 Login in github.com/zitadel/zitadel","modified":"2025-12-15T20:25:57.450163Z","packages":[{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":["<1.80.0-v2.20.0.20251208091519-4c879b47334e",">=1.83.4"],"fixed":["1.80.0-v2.20.0.20251208091519-4c879b47334e"]}]}],"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).
