{"id":"CVE-2025-24896","summary":"Misskey allows token to remain valid in cookie after signing out","details":"Misskey is an open source, federated social media platform. Starting in version 12.109.0 and prior to version 2025.2.0-alpha.0, a login token named `token` is stored in a cookie for authentication purposes in Bull Dashboard, but this remains undeleted even after logout is performed. The primary affected users will be users who have logged into Misskey using a public PC or someone else's device, but it's possible that users who have logged out of Misskey before lending their PC to someone else could also be affected. Version 2025.2.0-alpha.0 contains a fix for this issue.","aliases":["GHSA-w98m-j6hq-cwjm"],"modified":"2026-04-10T05:23:07.090344Z","published":"2025-02-11T15:14:09.305Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/24xxx/CVE-2025-24896.json","cwe_ids":["CWE-613"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/24xxx/CVE-2025-24896.json"},{"type":"ADVISORY","url":"https://github.com/misskey-dev/misskey/security/advisories/GHSA-w98m-j6hq-cwjm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-24896"},{"type":"FIX","url":"https://github.com/misskey-dev/misskey/commit/ba9f295ef2bf31cc90fa587e20b9a7655b7a1824"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/misskey-dev/misskey","events":[{"introduced":"2375359d129b63988b0658f735e1d9c014c10d71"},{"fixed":"89b461a5da42e6632a60c29796df6fb74d3cafd1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-24896.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/syuilo/misskey","events":[{"introduced":"2375359d129b63988b0658f735e1d9c014c10d71"},{"last_affected":"87b9016dbe75573db52ee03bbc67315caf8bbe6a"}],"database_specific":{"versions":[{"introduced":"12.109.0"},{"last_affected":"2025.1.0"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-24896.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"}]}
