Technical details
The vulnerability is a directory traversal flaw in the 'file' parameter that bypasses inadequate path validation. Although the plugin implements path confinement via strpos and realpath checks that restrict access to wp-content/uploads/, an attacker can still traverse within that directory to access unintended files without authentication. The attack vector is network-based with no authentication or user interaction required.
Affected products
