CVE-2025-5537
The Lightbox & Modal Popup WordPress Plugin – FooBox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via image alternative texts in all versions up to, and including, 2.7.34 due to insufficient input sanitization and output escaping.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
