{"schema":"threatline.record/2","record":{"id":"CVE-2026-115806","aliases":[],"summary":"Prime Mover <= 2.2.1 - Unauthenticated PHP Object Injection via Base64-Encoded Comment during Migration Search-and-Replace","details":"The Prime Mover – Backup and Migration plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.2.1 via deserialization of untrusted input in the migration search-and-replace routine (recursiveUnserializeReplace()). 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.","categories":["Unclassified"],"product":"Prime Mover – Backup and Migration","vendor":"codexonics","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115806","source_modified_at":"2026-10-24T04:32:10.565Z","fetched_at":"2026-10-24T05:41:33.294140Z","product":"Prime Mover – Backup and Migration","vendor":"codexonics","versions":[{"lessThanOrEqual":"2.2.1","status":"affected","version":"0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":9.8,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00819,"percentile":0.56855,"score_date":"2026-10-24"},"published_at":"2026-10-24T04:32:10.565Z","modified_at":"2026-10-24T04:32:10.565Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115806","fetched_at":"2026-10-24T05:41:33.294140Z","source_modified_at":"2026-10-24T04:32:10.565Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-115806","fetched_at":"2026-10-24T18:03:20.872036Z","source_modified_at":"2026-10-24"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/ab6ebd66-c7a4-402e-b51e-3f1f3183bd97?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/utilities/PrimeMoverSearchReplace.php#L1281"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/utilities/PrimeMoverSearchReplace.php#L391"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/vendor/freemius/includes/managers/class-fs-clone-manager.php#L1636"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/vendor/freemius/includes/managers/class-fs-option-manager.php#L414"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/utilities/PrimeMoverSearchReplace.php#L422"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/prime-mover/tags/2.2.1/utilities/PrimeMoverSearchReplace.php#L899"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-24T04:32:10.565Z","content_hash":"6d4800ce1316506ba7cbf03df92b62de7788e278fdc5af1e86ed145021b9b934"}}
