Vulnerability Overview

The Admin Columns Pro plugin for WordPress is vulnerable to CSV Injection via the export functionality in all versions up to, and including 6.4.9. This makes it possible for authenticated attackers, with subscriber-level access and above, to embed untrusted input into their profile that may appear in an exported CSV files. This can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration. While the CVE references the free version of the plugin, we did not find any export functionality in the free version which leads us to believe this is only present in the premium version.
