Description

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.
