Name of the Vulnerable Software and Affected Versions Taskbuilder – WordPress Project Management & Task Management plugin versions prior to 5.0.3

Attackers can inject arbitrary HTML and CSS through the comment body parameter via the wppm submit proj comment and wppm submit task comment AJAX actions.

Recommendations Update Taskbuilder – WordPress Project Management & Task Management plugin to version 5.0.3 or later.
