An unauthenticated attacker can store a crafted, base64-encoded serialized object in wp_comments.comment_content through the standard comment-submission endpoint (wp-comments-post.php). When an administrator subsequently performs a routine Prime Mover export or restore, the plugin base64-decodes that stored value and passes it to unserialize() with no allowed_classes restriction. A Property-Oriented Programming (POP) chain is present in the plugin's own bundled Freemius library (FS_Clone_Manager::__set → FS_Option_Manager::set_option → store() → update_option()), so no additional plugin or theme is required — the plugin ships the gadget itself.","state":0,"publishedAt":"2026-10-24T04:32:10.565+00:00","modifiedAt":"2026-10-24T04:32:10.565+00:00","affected":[{"ecosystem":"Vendor product","name":"Prime Mover – Backup and Migration","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"codexonics\",\n                    \"product\": \"Prime Mover – Backup and Migration\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"2.2.1\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ab6ebd66-c7a4-402e-b51e-3f1f3183bd97?source=cve","https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/utilities/PrimeMoverSearchReplace.php#L1281","https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/utilities/PrimeMoverSearchReplace.php#L391","https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/vendor/freemius/includes/managers/class-fs-clone-manager.php#L1636","https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/vendor/freemius/includes/managers/class-fs-option-manager.php#L414","https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/utilities/PrimeMoverSearchReplace.php#L422","https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/utilities/PrimeMoverSearchReplace.php#L899"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115806","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115806","identifiers":["CVE-2026-115806"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
