{"id":"CVE-2025-53895","state":"PUBLISHED","title":"ZITADEL has broken authN and authZ in session API and resulting session tokens","description":"ZITADEL is an open source identity management system. Starting in version 2.53.0 and prior to versions 4.0.0-rc.2, 3.3.2, 2.71.13, and 2.70.14, vulnerability in ZITADEL's session management API allows any authenticated user to update a session if they know its ID, due to a missing permission check. This flaw enables session hijacking, allowing an attacker to impersonate another user and access sensitive resources. Versions prior to `2.53.0` are not affected, as they required the session token for updates. Versions 4.0.0-rc.2, 3.3.2, 2.71.13, and 2.70.14 fix the issue.","publishedAt":"2025-07-15T16:39:00.635Z","updatedAt":"2025-07-15T17:19:29.391Z","severity":{"score":7.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["zitadel zitadel"],"affected":[{"vendor":"zitadel","product":"zitadel","versions":[{"version":"= 4.0.0-rc.1","status":"affected"},{"version":">= 3.0.0, < 3.3.1","status":"affected"},{"version":">= 2.53.0, < 2.70.14","status":"affected"},{"version":">= 2.71.0, < 2.71.13","status":"affected"}]}],"references":["https://github.com/zitadel/zitadel/security/advisories/GHSA-6c5p-6www-pcmr","https://github.com/zitadel/zitadel/releases/tag/v2.70.14","https://github.com/zitadel/zitadel/releases/tag/v2.71.13","https://github.com/zitadel/zitadel/releases/tag/v3.3.2","https://github.com/zitadel/zitadel/releases/tag/v4.0.0-rc.2"],"weaknesses":["CWE-863","CWE-384"],"ingestedAt":"2026-10-29T20:09:31.862Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/53xxx/CVE-2025-53895.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-53895","state":"PUBLISHED","datePublished":"2025-07-15T16:39:00.635Z","dateUpdated":"2025-07-15T17:19:29.391Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-07-11T19:05:23.825Z"},"containers":{"cna":{"title":"ZITADEL has broken authN and authZ in session API and resulting session tokens","descriptions":[{"lang":"en","value":"ZITADEL is an open source identity management system.
