CVE-2026-101889: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Codexonics Prime Mover
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.
AI Analysis
Technical Summary
The Prime Mover plugin for WordPress versions prior to 2.2.1 contains an improper limitation of a pathname to a restricted directory vulnerability (path traversal). The vulnerability arises due to insufficient path validation in the functions computeExtractVariables() and validateImportedSiteVsPackage(), which are exploited by manipulating the tar_root_folder values in the wprime-config.json file of a crafted WPRIME/TAR package. This manipulation causes the primeMoverDoDelete() function to delete directories outside the intended extraction path, including critical WordPress directories.
Potential Impact
An authenticated administrator can delete arbitrary directories on the WordPress server by exploiting this vulnerability. This can result in deletion of essential WordPress files and directories such as wp-admin, potentially causing site inoperability and disruption of service.
Mitigation Recommendations
A fix is available in Prime Mover version 2.2.1. Users should upgrade to version 2.2.1 or later to remediate this vulnerability.
