CVE-2026-86612Network attack vectorHinoki check available

Unauthenticated shortcode execution via untrusted form entries

Published Sep 23, 2026 · Updated Sep 23, 2026

Shortcode injection in Ninja Tables before 5.2.17 allows remote attackers to execute arbitrary shortcodes through public form entries. Fluent Forms-backed table rendering expands shortcode syntax from row values without restricting expansion to administrator-authored rows. Exploitation requires the non-default Fluent Forms data source on a public table; a crafted entry can invoke installed shortcode handlers and permanently break that page.
