Technical details

The WS Form LITE plugin for WordPress fails to implement adequate authorization checks (capability checks) on the 'wsf-settings-update' action. While the plugin uses a nonce for CSRF protection, this nonce is exposed to all logged-in users, including those with the 'Subscriber' role. An authenticated attacker can retrieve this nonce from the WordPress dashboard and send a crafted POST request to 'wp-admin' to overwrite plugin settings. Impacted settings include reCAPTCHA keys, Google Maps API keys, and IP-lookup URLs. The issue is resolved in version 1.11.8.
