{"id":"CVE-2025-24973","state":"PUBLISHED","title":"Concorde not removing authentication tokens after logging out","description":"Concorde, formerly know as Nexkey, is a fork of the federated microblogging platform Misskey. Prior to version 12.25Q1.1, due to an improper implementation of the logout process, authentication credentials remain in cookies even after a user has explicitly logged out, which may allow an attacker to steal authentication tokens. This could have devastating consequences if a user with admin privileges is (or was) using a shared device. Users who have logged in on a shared device should go to Settings > Security and regenerate their login tokens. Version 12.25Q1.1 fixes the issue. As a workaround, clear cookies and site data in the browser after logging out.","publishedAt":"2025-02-11T15:41:41.811Z","updatedAt":"2025-02-11T16:12:06.824Z","severity":{"score":9.4,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["nexryai concorde"],"affected":[{"vendor":"nexryai","product":"concorde","versions":[{"version":"< 12.25Q1.1","status":"affected"}]}],"references":["https://github.com/nexryai/concorde/security/advisories/GHSA-2369-p2wh-7cc2","https://github.com/nexryai/concorde/commit/1f6ac9b289906083b132e4f9667a31a60ef83e4e"],"weaknesses":["CWE-613"],"ingestedAt":"2026-10-29T20:08:47.682Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/24xxx/CVE-2025-24973.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-24973","state":"PUBLISHED","datePublished":"2025-02-11T15:41:41.811Z","dateUpdated":"2025-02-11T16:12:06.824Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-01-29T15:18:03.211Z"},"containers":{"cna":{"title":"Concorde not removing authentication tokens after logging out","descriptions":[{"lang":"en","value":"Concorde, formerly know as Nexkey, is a fork of the federated microblogging platform Misskey.
