{"id":"CVE-2026-56665","summary":"ZITADEL: Missing Token Expiration (`exp`) Validation in JWT IdP Provider","details":"ZITADEL is an open source identity management platform. Prior to 3.4.12 and 4.15.2, ZITADEL is an open source identity management platform. From 3.0.0-rc.1 through 3.4.11 and from 4.0.0-rc.1 through 4.15.1, ZITADEL's external JWT Identity Provider validation in internal/idp/providers/jwt/session.go skips expiration handling when an incoming token omits the exp claim, allowing a token from a trusted issuer to be treated as valid without an automatic expiration window. This issue is fixed in versions 3.4.12 and 4.15.2.","aliases":["GHSA-v77h-2w3m-94hx"],"modified":"2026-07-15T01:48:56.122017895Z","published":"2026-07-10T17:22:46.079Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56665.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-613"]},"references":[{"type":"WEB","url":"https://github.com/zitadel/zitadel/releases/tag/v3.4.12"},{"type":"WEB","url":"https://github.com/zitadel/zitadel/releases/tag/v4.15.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56665.json"},{"type":"ADVISORY","url":"https://github.com/zitadel/zitadel/security/advisories/GHSA-v77h-2w3m-94hx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56665"},{"type":"FIX","url":"https://github.com/zitadel/zitadel/commit/4925fab849d39a88674485d937b79e54318b48a8"},{"type":"FIX","url":"https://github.com/zitadel/zitadel/commit/d1c3aa84af8fcb0f33910ada30b866f4afb551ac"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/zitadel/zitadel","events":[{"introduced":"0f0a55ca18873b85feaca561e6f0b3f081ad4204"},{"fixed":"90f310212d3a5075084a603bf61fed549c92956d"},{"introduced":"8f0b7ebf028187e84881694bb931cbe33604e308"},{"fixed":"a1748b2f0326ddf7be0de44b4f980ae2c07c0151"},{"fixed":"4925fab849d39a88674485d937b79e54318b48a8"},{"fixed":"d1c3aa84af8fcb0f33910ada30b866f4afb551ac"},{"fixed":"c6b7e67548cfec209d7e22cd6256b04ca6b02995"},{"fixed":"c53d9774d4272d3cebeee4131012c20bd77b9dfb"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"3.0.0-rc.1"},{"fixed":"3.4.11"},{"introduced":"4.0.0-rc.1"},{"fixed":"4.15.1"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-56665.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
