ITW EXPLOIT VulnCheck KEV

The Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag & Drop WP Form Builder plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the /wp-json/fluentform/v1/global-settings REST API endpoint in all versions up to, and including, 5.1.16. This makes it possible for unauthenticated attackers to modify all of the plugin's settings.

url /wp-json/fluentform/v1/global-settings↗

path /wp-content/plugins/fluentform/↗

command POST /wp-json/fluentform/v1/global-settings HTTP/1.1 Content-Type: application/json {"key": "emailSummarySettings", "email_report": {"status": "yes", "send_to_type": "custom", "custom_recipients": "{{email}}", "sending_day": "Mon"}}

• → Detect unauthenticated POST requests to the Fluent Forms global-settings REST endpoint; no authentication headers should be present. ↗
• → Fingerprint vulnerable WordPress installations by searching for the string /wp-content/plugins/fluentform/ in HTTP response bodies.
• → The attack payload targets the JSON key 'emailSummarySettings' to redirect email reports to an attacker-controlled address; monitor for unexpected changes to this setting.

• · The vulnerability affects all plugin versions up to and including 5.1.16; version 5.1.17 and later are patched. ↗
• · The Nuclei template is marked 'intrusive' because it actively modifies plugin settings (emailSummarySettings) on the target; use only in authorized testing environments.
