{"id":"CVE-2023-22492","aliases":["GHSA-6rrr-78xp-5jp8"],"url":"https://o3.security/vulnerability/CVE-2023-22492","summary":"RefreshToken invalidation vulnerability","details":"### Impact\nRefreshTokens is an OAuth 2.0 feature that allows applications to retrieve new access tokens and refresh the user's session without the need for interacting with a UI.\n\nRefreshTokens were not invalidated when a user was locked or deactivated. The deactivated or locked user was able to obtain a valid access token only through a refresh token grant.\n\nWhen the locked or deactivated user’s session was already terminated (“logged out”) then it was not possible to create a new session. Renewal of access token through a refresh token grant is limited to the configured amount of time (RefreshTokenExpiration).\n\n### Patches\n2.x versions are fixed on >= [2.17.3](https://github.com/zitadel/zitadel/releases/tag/v2.17.3)\n2.16.x versions are fixed on >= [2.16.4](https://github.com/zitadel/zitadel/releases/tag/v2.16.4)\n\nZITADEL recommends upgrading to the latest versions available in due course.\n\n### Workarounds\nEnsure the RefreshTokenExpiration in the OIDC settings of your instance is set according to your security requirements.\n\n### References\n\nhttps://zitadel.com/docs/guides/manage/console/instance-settings#oidc-token-lifetimes-and-expiration\n","published":"2023-01-11T19:42:50.505Z","modified":"2026-08-12T03:51:45.709620550Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/zitadel/zitadel","fixedVersion":"2.17.3"},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","fixedVersion":"2.16.4"}],"fix":{"url":"https://github.com/zitadel/zitadel/commit/301e22c4956ead6014a8179463c37263f7301a83","label":"zitadel/zitadel@301e22c"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/22xxx/CVE-2023-22492.json"},{"type":"ADVISORY","url":"https://github.com/zitadel/zitadel/security/advisories/GHSA-6rrr-78xp-5jp8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-22492"},{"type":"FIX","url":"https://github.com/zitadel/zitadel/commit/301e22c4956ead6014a8179463c37263f7301a83"},{"type":"FIX","url":"https://github.com/zitadel/zitadel/commit/fc892c52a10cd4ffdac395747494f3a93a7494c2"},{"type":"PACKAGE","url":"https://github.com/zitadel/zitadel"},{"type":"WEB","url":"https://github.com/zitadel/zitadel/releases/tag/v2.16.4"},{"type":"WEB","url":"https://github.com/zitadel/zitadel/releases/tag/v2.17.3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:45.709620550Z"}}
