Stored XSS via unverified form-field requests
Published May 5, 2021 · Updated Aug 3, 2024
Cross-site request forgery in Business Directory Plugin before 5.11.1 allows remote attackers to alter form fields through an administrator's session. The form-field administration actions accept add, edit, and delete requests without verifying a nonce or enforcing the proper capability, and attacker-supplied labels or descriptions can persist script markup. Exploitation requires a logged-in administrator to load attacker-controlled content; successful field changes can delete configuration or run stored script when affected directory and settings pages are viewed.
