Why it matters

This matters because the affected product may be exposed on public websites. A vulnerable plugin can create a direct path to site compromise, malicious code deployment, or data theft.

Recommended admin actions

• Review and patch based on exposure, asset criticality, and business impact.
• Check whether the affected WordPress plugin or theme is installed.
• Update, disable, or remove the affected component if present.
• Compare installed versions against the affected version range in the advisory.
• Treat internet-facing systems as higher priority.

Technical summary

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.
