CVE-2026-80437Network attack vector

Unauthenticated shortcode execution via unsanitized merge tags

Published Sep 6, 2026 · Updated Sep 6, 2026

Shortcode injection in Saturday Drive Ninja Forms 3.14.10 through 3.15.1 allows remote attackers to execute registered shortcodes. IP-address and referrer merge-tag substitution inserts request-derived values into content that the plugin passes to WordPress shortcode processing without neutralizing bracket syntax. No authentication is required, but a reachable form must process an affected merge tag; impact depends on the registered shortcode invoked.
