CyberRota Analysis
AI-GeneratedThe Firelight Lightbox plugin for WordPress is vulnerable to Stored DOM Cross-Site Scripting due to inadequate sanitization of the href attribute in the FancyBox V2 PDF beforeLoad JavaScript callback, allowing authenticated attackers with contributor-level access or higher to inject malicious scripts. This vulnerability can lead to arbitrary web scripts executing when users interact with the compromised PDF links, potentially compromising user data and session integrity. WordPress site administrators and developers using affected versions of the plugin should prioritize patching to mitigate this risk.
Original NVD Description
The Firelight Lightbox plugin for WordPress is vulnerable to Stored DOM Cross-Site Scripting in versions up to and including 2.3.20. This is due to insufficient sanitization of the href attribute value within the FancyBox V2 PDF beforeLoad JavaScript callback generated in inc/fancybox-2.php, where this.href is string-concatenated directly into an HTML string without escaping, allowing a stored href containing entity-encoded double-quotes to break out of the data attribute and inject arbitrary event handlers into the DOM. This makes it possible for authenticated attackers with contributor-level access and above to inject arbitrary web scripts into pages that execute whenever a user clicks the malicious PDF link.
