CVE-2024-11775 exposes a critical stored cross-site scripting (XSS) vulnerability within the Particle Background plugin for WordPress, specifically through the 'particleground' shortcode. This flaw arises from inadequate input sanitization and output escaping for user-supplied attributes, allowing authenticated attackers with contributor-level access or higher to inject malicious web scripts.

The vulnerability affects all versions of the plugin up to and including 1.0.2, necessitating prompt updates to ensure website safety and integrity.
