CVE-2024-4144Network attack vector

Unauthenticated shortcode execution via unvalidated form action

Published May 14, 2024 · Updated Apr 8, 2026

Code injection in WPKube Simple Basic Contact Form 20240502 and earlier allows remote attackers to execute arbitrary shortcodes. A public form action passes an insufficiently validated request value to WordPress do_shortcode(), causing supplied shortcode syntax to be evaluated. Unauthenticated access is sufficient; resulting effects depend on the shortcodes registered by other installed plugins.
