Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

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.
