CVE-2025-13897: AMU02AFTAB Client Testimonial Slider

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The Client Testimonial Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'aft_testimonial_meta_name' custom field in the Client Information metabox in all versions up to, and including, 2.0 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 the injected administrative page.

Affected products

• AMU02AFTAB Client Testimonial Slider: up to and including 2.0
