Lightbox With Photoswipe
Monthly
Stored XSS in the Lightbox with PhotoSwipe WordPress plugin before 5.9.0 allows author-level users (lacking unfiltered_html) to inject arbitrary JavaScript into image lightbox captions via an unsanitized link data attribute. The payload executes in the browser of any visitor or administrator who opens the affected lightbox, enabling session hijacking or privilege escalation against site administrators. A publicly available exploit documents the technique; no active exploitation is confirmed via CISA KEV, though the author-level entry bar is low on sites with multiple contributors.
