Summary

The Lightbox with PhotoSwipe WordPress plugin before version 5.9.0 does not sanitise or escape a link data attribute before rendering it into the image lightbox caption in the browser. Users with author-level access and above (who lack the unfiltered_html capability) can store JavaScript that runs when a visitor or administrator opens the lightbox.

Risk Assessment

An attacker with author privileges can inject a malicious script that executes in the browsers of administrators and visitors, leading to session theft or other harm.
