AI-suggested

Upgrade the CookieYes WordPress plugin to version 3.5.8 or later, where this vulnerability is fixed. Until then, restrict Contributor role permissions to prevent writing to cookie-category script fields or disable the plugin if possible. No vendor advisory or patch links are provided, so verify the availability of official fixes from the vendor.

Description

The CookieYes WordPress plugin versions prior to 3.5.8 have a vulnerability where users with the Contributor role can inject JavaScript into the cookie-category script fields. This occurs because the plugin does not properly restrict write access to these fields nor sanitize or escape the input, leading to potential cross-site scripting (XSS) attacks affecting site visitors and administrators reviewing content.
