Description

The Lightbox with PhotoSwipe WordPress plugin versions prior to 5.19.0 contain a vulnerability where link titles and other caption sources are not properly sanitized before being inserted as HTML into image lightbox captions. This flaw allows unauthenticated users to inject stored cross-site scripting (XSS) payloads via comments.
