Stored XSS via forged administrator settings update

Published Jan 16, 2025 · Updated May 11, 2026

Cross-site request forgery in jprintf CNZZ&51LA for WordPress 1.0.1 and earlier allows remote attackers to inject stored scripts. The plugin's settings-update function accepts forged requests without correct nonce validation and stores attacker-supplied script content. Exploitation requires a logged-in site administrator to visit a crafted page or link, after which the stored script executes for site visitors.
