{"id":"CVE-2026-45162","summary":"Pimcore: Unsafe PHP Deserialization in Multiple Locations Without allowed_classes Restriction","details":"Pimcore is an Open Source Data & Experience Management Platform. 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.","aliases":["GHSA-36fc-7wjg-mfvj"],"modified":"2026-07-24T03:57:02.751128520Z","published":"2026-07-17T18:50:19.924Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-502"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45162.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"11.5.17"}]}]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pimcore/pimcore","events":[{"introduced":"df14e025d3db615fc75b190e3c9f3cc1d68d7304"},{"fixed":"4788bf3a3a7f2f760a8fe61e522565941e154e1e"},{"fixed":"d8a4b30690369f5325879b9f969796d6a4f57fa3"}],"database_specific":{"extracted_events":[{"introduced":"12.0.0"},{"fixed":"12.3.7"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v12.3.5","v12.3.4","v12.3.3","v12.3.2","v12.3.1.1","v12.3.1","v12.3.0","v12.2.1","v12.2.0","v12.1.0","v12.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45162.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H"}]}
