AI Analysis
Technical Summary
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 advanced heading widget's typer effect. This vulnerability allows authenticated users with contributor-level permissions or higher to inject arbitrary web scripts due to insufficient sanitization and escaping of user-supplied attributes. The injected scripts execute in the context of any user who accesses the compromised page. The vulnerability affects all versions up to 3.2.37 and has a CVSS 3.1 base score of 6.4 (medium severity). No patch or official fix information is currently available, and no known exploits have been reported.
Potential Impact
An attacker with contributor-level access or higher can exploit this vulnerability to inject malicious scripts that execute in the browsers of users viewing the affected pages. This can lead to unauthorized actions such as session hijacking or defacement limited to the scope of the injected scripts. The vulnerability does not impact availability but can compromise confidentiality and integrity to a limited extent. No known exploitation in the wild has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or avoiding use of the advanced heading widget's typer effect. Monitor official channels from stellarwp for updates and apply patches promptly once released.
