Detailsinfo

A vulnerability classified as problematic has been found in Codexonics Prime Mover Plugin up to 2.2.0. Affected is the function computeExtractVariables/validateImportedSiteVsPackage of the file wprime-config.json of the component Path Validation. The manipulation of the argument tar_root_folder with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on integrity, and availability. CVE summarizes:

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.

The advisory is available at wordpress.org. This vulnerability is traded as CVE-2026-101889 since 09/28/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Additional levels of successful authentication are required for exploitation. Successful exploitation requires user interaction by the victim.
