{"id":"CVE-2025-24896","state":"PUBLISHED","title":"Misskey allows token to remain valid in cookie after signing out","description":"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.","publishedAt":"2025-02-11T15:14:09.305Z","updatedAt":"2025-02-12T20:51:44.328Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["misskey-dev misskey"],"affected":[{"vendor":"misskey-dev","product":"misskey","versions":[{"version":">= 12.109.0, < 2025.2.0-alpha.0","status":"affected"}]}],"references":["https://github.com/misskey-dev/misskey/security/advisories/GHSA-w98m-j6hq-cwjm","https://github.com/misskey-dev/misskey/commit/ba9f295ef2bf31cc90fa587e20b9a7655b7a1824"],"weaknesses":["CWE-613"],"ingestedAt":"2026-10-29T20:08:47.682Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/24xxx/CVE-2025-24896.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-24896","state":"PUBLISHED","datePublished":"2025-02-11T15:14:09.305Z","dateUpdated":"2025-02-12T20:51:44.328Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-01-27T15:32:29.451Z"},"containers":{"cna":{"title":"Misskey allows token to remain valid in cookie after signing out","descriptions":[{"lang":"en","value":"Misskey is an open source, federated social media platform.
