CVE-2026-6454: Firelight PDF links allow contributor stored DOM XSS

A contributor can store a PDF link whose entity-encoded quotes break out when Firelight Lightbox's FancyBox V2 beforeLoad callback concatenates this.href into object/embed HTML. The resulting event-handler markup executes when a visitor clicks the link. The CNA lists releases through 2.3.20 as affected, although the currently served official 2.3.20 package already uses safe jQuery element construction while 2.3.18 is demonstrably vulnerable.
