The ProSolution WP Client WordPress plugin before 2.0.11 does not sanitise and escape a parameter before reflecting it into an HTML attribute on one of its administrative pages, leading to reflected Cross-Site Scripting that runs in the session of an administrator induced to submit a crafted request.

Reflected Cross-Site Scripting in the ProSolution WP Client WordPress plugin (versions before 2.0.11) allows an unauthenticated remote attacker to execute arbitrary JavaScript in the browser session of an authenticated WordPress administrator by inducing them to submit a specially crafted request targeting an affected administrative page. The unsanitized parameter is reflected directly into an HTML attribute without escaping, satisfying CWE-79. …
