{"id":"CVE-2025-43819","aliases":["GHSA-rpx3-f938-xj5q"],"url":"https://o3.security/vulnerability/CVE-2025-43819","summary":"Liferay Portal and DXP does not properly expire sessions","details":"### Summary\n\nLiferay Portal/DXP contains an Insufficient Session Expiration issue where the Single Logout (SLO) API may fail to invalidate a user’s previous session. An attacker can reuse a stale session via the SLO endpoint to gain an authenticated context.\n\n### Affected Versions\n\nThe following platform versions are affected:\n\n*   **Liferay Portal:**  \n    *   `7.3.3.131` through `7.4.3.121`\n*   **Liferay DXP:**\n    *   `2024.Q4.0`–`2024.Q4.3`\n    *   `2024.Q3.1`–`2024.Q3.13`\n    *   `2024.Q2.0`–`2024.Q2.13`\n    *   `2024.Q1.1`–`2024.Q1.12`\n\n### Remediation\n\nUpdate to the fixed builds and, for Maven consumers of the SAML module, upgrade `com.liferay:com.liferay.saml.impl` to **5.0.51** or later. After upgrading, ensure session invalidation policies are enforced and verify SLO behavior end-to-end.","published":"2025-09-24T02:15:31.107Z","modified":"2026-09-05T08:10:15.926992Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"com.liferay:com.liferay.saml.impl","fixedVersion":"5.0.51"}],"fix":{"url":"https://github.com/liferay/liferay-portal/commit/433dff5edae4414fdc436b49a9edb62d721c84b5","label":"liferay/liferay-portal@433dff5"},"references":[{"type":"ADVISORY","url":"https://liferay.dev/portal/security/known-vulnerabilities/-/asset_publisher/jekt/content/CVE-2025-43819"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-43819"},{"type":"WEB","url":"https://github.com/liferay/liferay-portal/commit/433dff5edae4414fdc436b49a9edb62d721c84b5"},{"type":"WEB","url":"https://github.com/liferay/liferay-portal/commit/da9105a61d788801797797a32583a4b76c902cdc"},{"type":"PACKAGE","url":"https://github.com/liferay/liferay-portal"},{"type":"WEB","url":"https://liferay.atlassian.net/browse/LPE-18159"},{"type":"WEB","url":"https://osv.dev/vulnerability/GHSA-rpx3-f938-xj5q"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-05T08:10:15.926992Z"}}
