The Gutenberg Blocks with AI by Kadence WP – Page Builder Features plugin for WordPress contains a stored cross-site scripting vulnerability (CWE-79) in its Icon widget. This occurs because the plugin fails to properly sanitize and escape user input attributes before rendering them on web pages. Authenticated attackers with contributor-level permissions or higher can exploit this to inject arbitrary JavaScript code that executes in the context of users viewing the compromised pages. The vulnerability affects all versions up to 6.6.2. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impact on confidentiality and integrity but not availability. No patch or remediation details are currently available from the vendor.

An attacker with contributor-level access or higher can inject persistent malicious scripts into pages via the Icon widget. These scripts execute in the browsers of users who view the infected pages, potentially leading to data disclosure or integrity compromise within the affected WordPress site context. There is no indication of availability impact. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the vulnerable Icon widget if feasible. Monitor vendor channels for updates and apply patches promptly once available.
