CVE-2026-4665Network attack vector

Contributor-level stored XSS via caption fallback

Published May 5, 2026 · Updated May 5, 2026

Stored XSS in ShapedPlugin WP Carousel 2.7.10 and earlier allows remote authenticated users to execute scripts via crafted carousel markup. The fancybox configuration passes a DOM-derived carousel ID into a jQuery selector without validation; malformed selector syntax aborts initialization, leaving bundled Fancybox to render data-caption content as raw HTML. Contributor-level access is required to store the markup, and a visitor must click an affected carousel image before the script runs in that visitor's browser.
