Detection Guidance

This vulnerability arises from missing authorization, authentication, or nonce token checks within certain functions of the WP Forms Signature Contract Add-On Plugin versions up to 1.8.2.

Detection would involve verifying the plugin version installed on your WordPress system and checking for unauthorized access attempts or actions performed by users with Subscriber or Developer roles that should be restricted.

Since the vulnerability is related to broken access control in the plugin, you can detect it by running commands to identify the plugin version, such as:

• Use WP-CLI to check the plugin version: `wp plugin list | grep wp-forms-signature-contract-add-on`
• Review web server logs for suspicious requests or actions performed by low-privileged users that should require higher privileges.
• Monitor WordPress user roles and permissions to detect any unauthorized privilege escalations or actions.
