Executive Summary

This is a Missing Authorization vulnerability in the WP E-Signature Ninja Forms Signature Contract Add-On. It allows unauthenticated users to access restricted pages or perform unauthorized actions due to incorrectly configured access control security levels. The vulnerability affects versions up to 3.2.5.

Detection Guidance

Check if the WordPress Ninja Forms Signature Contract Add-On plugin version is 3.2.5 or below. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files in the /wp-content/plugins/ directory for version details.

Impact Analysis

An attacker could exploit this to access sensitive data or perform actions they shouldn't be able to. Since it requires no authentication, the risk is higher for exposed systems. The impact is limited by a low CVSS score of 5.3.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, which may violate GDPR or HIPAA requirements for data protection and access controls. Compliance could be compromised if unauthorized access occurs.

Mitigation Strategies

Update the plugin to version 3.2.5.1 or later immediately. Enable auto-update features if available. Remove or disable the plugin if an update is not possible.
