What is CVE-2026-16260?

The Post Grid, Slider & Carousel Ultimate plugin for WordPress prior to version 1.8.1 is susceptible to a JavaScript injection vulnerability. This flaw arises from the plugin's failure to properly sanitize and escape specific custom post type settings prior to rendering them in HTML attributes on the admin edit screen. As a result, contributors and users with higher roles can exploit this vulnerability by injecting malicious JavaScript. When an administrator accesses the affected settings, the injected script executes within their session, posing significant security risks such as unauthorized access or data manipulation.
