CVE-2026-6454
Medium · 6.4
CWE-79 Jul 24, 2026
Firelight Lightbox <= 2.3.20 - Authenticated (Contributor+) Stored DOM Cross-Site Scripting via PDF beforeLoad 'href' Attribute
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.
CVE-2026-4379
Medium · 6.4
CWE-79 Apr 8, 2026
LightPress Lightbox <= 2.3.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'group' Shortcode Attribute
The LightPress Lightbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `group` attribute in the `[gallery]` shortcode in all versions up to, and including, 2.3.4. This is due to the plugin modifying gallery shortcode output to include the `group` attribute value without proper escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
