Executive Summary

This vulnerability is a Subscriber Insecure Direct Object Reference (IDOR) issue found in WC Ukraine Shipping plugin versions up to and including 1.22.3. IDOR occurs when an application exposes direct references to internal objects, allowing attackers to manipulate these references to access unauthorized data.

Detection Guidance

To detect this IDOR vulnerability in the WC Ukraine Shipping Plugin, inspect plugin files for direct object references in API endpoints or database queries. Check for missing authorization checks in functions handling user data. Review server logs for unusual access patterns to sensitive endpoints. Use tools like WPScan or manual code review to identify unprotected direct object references.

Impact Analysis

An attacker could exploit this IDOR vulnerability to access sensitive subscriber data or perform unauthorized actions on behalf of other users. This could lead to data breaches, privacy violations, or unauthorized modifications to shipping or account information.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA by exposing personal or health-related data to unauthorized parties. GDPR requires protecting personal data, while HIPAA mandates safeguarding protected health information. A breach could result in legal penalties and reputational damage.

Mitigation Strategies

Update WC Ukraine Shipping to the latest version to address the IDOR vulnerability. Ensure proper access controls are implemented to prevent unauthorized object references. Regularly audit user permissions and restrict sensitive data access.
