Deeper analysis
The File Manager Pro – Filester plugin for WordPress is vulnerable to arbitrary file uploads due to missing validation in the 'fsConnector' function in all versions up to and including 1.8.6. The issue, tracked as CWE-434, affects the plugin's file handling logic and carries a CVSS 3.1 score of 7.5.
