CVE-2026-2716: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in amu02aftab Client Testimonial Slider
The Client Testimonial Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Testimonial Heading' setting in all versions up to, and including, 2.0. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Technical Summary
CVE-2026-2716 is a stored cross-site scripting vulnerability (CWE-79) in the Client Testimonial Slider WordPress plugin (amu02aftab project). The flaw exists in the 'Testimonial Heading' setting due to improper neutralization of input during web page generation. Authenticated attackers with Administrator privileges can inject arbitrary scripts that execute in the context of users visiting the injected pages. This vulnerability affects all plugin versions up to and including 2.0, specifically in multi-site environments or where unfiltered_html is disabled. There is no indication of known exploits in the wild or available patches.
Potential Impact
Successful exploitation allows an authenticated administrator-level user to inject and execute arbitrary JavaScript in the context of other users visiting the affected pages. This can lead to information disclosure or limited integrity impact within the affected WordPress environment. The vulnerability does not affect availability and requires high privileges and specific configuration (multi-site or unfiltered_html disabled).
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory for updates. Until a fix is released, restrict administrator access to trusted users only and consider disabling or removing the Client Testimonial Slider plugin in multi-site environments or where unfiltered_html is disabled to prevent exploitation.
