Summary
The Firelight Lightbox WordPress plugin before 2.3.24 does not properly escape image attribute values before processing them in the browser. This could allow users with contributor-level access and above to inject arbitrary web scripts that execute when another user views or previews the affected content.
Risk Assessment
An attacker with contributor-level access can inject malicious scripts that execute in other users' browsers, including administrators. This may lead to session hijacking or unauthorized actions.
Recommendation
Update the Firelight Lightbox plugin to version 2.3.24 or later. Review content created by contributor-level users for suspicious scripts.
