Description

WordPress Plugin Testimonial Slider and Showcase 2.2.6 contains a stored cross-site scripting vulnerability that allows authenticated editors to inject malicious scripts by failing to sanitize the post_title parameter. Attackers with editor privileges can inject JavaScript payloads through the testimonial title field that execute in the browsers of users viewing the draft post, enabling cookie theft and session hijacking.
