SKT Blocks WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the SKT Blocks Gutenberg-based Page Builder plugin for WordPress, affecting all versions through 1.7. The issue arises in the 'post-carousel' block, where inadequate input sanitization and output escaping allow authenticated attackers with contributor-level access or higher to inject arbitrary scripts. These scripts are executed when a user accesses the affected page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Remediation

Users can update to version 1.8 or a newer patched version to address this vulnerability.
