Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Axelerant Testimonials Widget allows Stored XSS.This issue affects Testimonials Widget: from n/a through 4.0.4.

The Testimonials Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's testimonials shortcode in all versions up to, and including, 4.0.4 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WP Responsive Testimonials Slider And Widget WordPress plugin through 1.5 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

Unvalidated input and lack of output encoding in the Testimonials Widget WordPress plugin, versions before 4.0.0, lead to multiple Cross-Site Scripting vulnerabilities, allowing remote attackers to inject arbitrary JavaScript code or HTML via the below parameters: - Author - Job Title - Location - Company - Email - URL
