{"id":"CVE-2025-46336","aliases":["GHSA-9j94-67jr-4cqj"],"url":"https://o3.security/vulnerability/CVE-2025-46336","summary":"Rack session gets restored after deletion","details":"Rack::Session is a session management implementation for Rack. In versions starting from 2.0.0 to before 2.1.1, when using the Rack::Session::Pool middleware, and provided the attacker can acquire a session cookie (already a major issue), the session may be restored if the attacker can trigger a long running request (within that same session) adjacent to the user logging out, in order to retain illicit access even after a user has attempted to logout. This issue has been patched in version 2.1.1.","published":"2025-05-08T19:26:01.638Z","modified":"2026-07-15T01:49:02.539100132Z","cvss":{"score":4.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"RubyGems","name":"rack-session","fixedVersion":"2.1.1"}],"fix":{"url":"https://github.com/rack/rack-session/commit/c28c4a8c1861d814e09f2ae48264ac4c40be2d3b","label":"rack/rack-session@c28c4a8"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/46xxx/CVE-2025-46336.json"},{"type":"ADVISORY","url":"https://github.com/rack/rack-session/security/advisories/GHSA-9j94-67jr-4cqj"},{"type":"ADVISORY","url":"https://github.com/rack/rack/security/advisories/GHSA-vpfw-47h7-xj4g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-46336"},{"type":"FIX","url":"https://github.com/rack/rack-session/commit/c28c4a8c1861d814e09f2ae48264ac4c40be2d3b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:02.539100132Z"}}
