CVE-2024-0662: Colorlib Fancybox

Medium severity, CVSS 4.8. EPSS: 0.5% chance of exploitation in the next 30 days.

The FancyBox for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions 3.0.2 to 3.3.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Affected products

• Colorlib Fancybox: from 3.0.2, before 3.3.3 (fixed in 3.3.3)
