Prior to 11.5.17 (LTS) and 12.3.7, multiple Pimcore locations call PHP's unserialize() on data from database columns and filesystem files without the allowed_classes restriction, including lib/Tool/Authentication.php, models/Site/Dao.php, models/DataObject/ClassDefinition/CustomLayout/Dao.php, models/Tool/TmpStore/Dao.php, models/Asset/WebDAV/Service.php, and admin-ui-classic-bundle/src/Helper/Dashboard.php, enabling object injection and remote code execution if an attacker can control the serialized data source. This issue is fixed in versions 11.5.17 (LTS) and 12.3.7.","published":"2026-07-17T18:50:19.924Z","modified":"2026-08-12T03:51:31.987460094Z","cvss":{"score":8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H"},"epss":{"score":0.00574,"percentile":0.44664,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"pimcore/pimcore","fixedVersion":"12.3.7"},{"ecosystem":"Packagist","name":"pimcore/pimcore","fixedVersion":"11.5.17"},{"ecosystem":"Packagist","name":"pimcore/pimcore","fixedVersion":"2026.1.3"}],"fix":{"url":"https://github.com/pimcore/pimcore/commit/4788bf3a3a7f2f760a8fe61e522565941e154e1e","label":"pimcore/pimcore@4788bf3"},"references":[{"type":"WEB","url":"https://github.com/pimcore/pimcore/releases/tag/v12.3.7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45162.json"},{"type":"ADVISORY","url":"https://github.com/pimcore/pimcore/security/advisories/GHSA-36fc-7wjg-mfvj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45162"},{"type":"FIX","url":"https://github.com/pimcore/pimcore/commit/4788bf3a3a7f2f760a8fe61e522565941e154e1e"},{"type":"FIX","url":"https://github.com/pimcore/pimcore/pull/19119"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:31.987460094Z"}}
