Description

The Task Manager plugin for WordPress is vulnerable to arbitrary shortcode execution via the &#39;search&#39; AJAX action in all versions up to, and including, 3.0.2. This is due to missing capability checks in the callback_search() function and insufficient input validation that allows shortcode syntax (square brackets) to pass through sanitize_text_field() and be concatenated into a do_shortcode() call. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes on the site by injecting shortcode syntax into parameters like &#39;task_id&#39;, &#39;point_id&#39;, &#39;categories_id&#39;, or &#39;term&#39;.
