What is CVE-2025-1664?

The Essential Blocks plugin for WordPress has a vulnerability that allows authenticated users with Contributor access or higher to execute arbitrary web scripts through the Parallax slider feature. This occurs due to inadequate input sanitization and output escaping, creating opportunities for injected scripts to run whenever a page containing the vulnerable block is accessed. It is crucial for users to update to version 5.3.2 or later to mitigate this risk.
