CVE-2024-12417Network attack vector

Unauthenticated shortcode execution via unvalidated embed action

Published Dec 13, 2024 · Updated Apr 8, 2026

Arbitrary shortcode execution in QuantumCloud Simple Link Directory 8.4.5 and earlier allows remote attackers to run registered shortcodes. The embed handler in embed/qcopd-embed-link.php invokes do_shortcode after insufficiently validating an attacker-supplied action value. No authentication or user interaction is required; resulting access or modification is limited to capabilities exposed by installed shortcodes.
