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 1.9. 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 views the affected page.

Remediation

Users can update to version 2.0 or a newer patched version to address this vulnerability.
