## What is CVE-2026-101888?

CVE-2026-101888 is a high-severity path traversal vulnerability in Codexonics Prime Mover, published on 1 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official 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.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)
