Name of the Vulnerable Software and Affected Versions Client Testimonial Slider plugin for WordPress versions prior to 2.1

Description The Client Testimonial Slider plugin for WordPress is susceptible to Stored Cross-Site Scripting through the 'Testimonial Heading' setting. Insufficient input sanitization and output escaping allow authenticated attackers with Administrator-level access or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the affected page. This issue specifically impacts multi-site installations and installations where unfiltered html has been disabled.

Recommendations Update the Client Testimonial Slider plugin to version 2.1 or later.
