Oct 24, 2026Prime Mover – Backup and Migration: PHP Object InjectionCVE-2026-115806 · affects up to 2.2.1 · reported by WordfenceCritical 9.8
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.

Oct 1, 2026The Prime Mover: Stored cross-site scriptingCVE-2026-101890 · fixed in 2.2.1 · reported by VulnCheckMedium 5.1
The Prime Mover plugin for WordPress before 2.2.1 contains a stored cross-site scripting vulnerability that allows attackers to execute arbitrary JavaScript by injecting an unescaped site_title value in a package's footprint.json file. Attackers can place a crafted package under the prime-mover-export-files directory so that the malicious value renders unescaped in the column_site_title() method of PrimeMoverBackupMenuListTable.php, triggering script execution in an administrator's browser when they view the Prime Mover Packages list table without needing to restore the package.
Oct 1, 2026The Prime Mover: Path traversalCVE-2026-101889 · fixed in 2.2.1 · reported by VulnCheckHigh 7
The Prime Mover plugin for WordPress before 2.2.1 contains a path traversal vulnerability that allows authenticated administrators to delete arbitrary directories by importing a crafted WPRIME/TAR package with manipulated tar_root_folder values in wprime-config.json. Attackers can exploit insufficient path validation in computeExtractVariables() and validateImportedSiteVsPackage() to cause primeMoverDoDelete() to remove directories outside the intended extraction path, potentially deleting critical WordPress directories such as wp-admin and rendering the site inoperable.
Oct 1, 2026The Prime Mover: Zip Slip path traversalCVE-2026-101888 · fixed in 2.2.1 · reported by VulnCheckHigh 8.6
The Prime Mover plugin for WordPress before 2.2.1 contains a Zip Slip path traversal vulnerability that allows authenticated administrators to write arbitrary files outside the intended extraction directory during migration ZIP import. Attackers can craft ZIP entry names with traversal sequences processed by computeExtractionParameters() and resumableZipExtractor() in utilities/PrimeMoverSystemCheckUtilities.php to write attacker-controlled content to arbitrary filesystem locations, potentially achieving remote code execution if the written files are interpreted by the web environment.
