Executive Summary

This vulnerability is an Insecure Direct Object Reference (IDOR) flaw in the ShopApper Mobile App Builder Service for WooCommerce WordPress plugin. It allows any authenticated user, including subscribers, to access other users' personal data such as email addresses, names, and roles by querying a REST endpoint without proper ownership verification.

Detection Guidance

To detect this vulnerability, check if your WooCommerce Mobile App plugin version is 0.4.66 or below. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files for version details. Test REST endpoints for unauthorized data access by querying user endpoints with different user IDs.

Impact Analysis

This vulnerability can expose sensitive personal data of users, including email addresses, names, and roles. If you use the affected plugin versions, attackers with basic authentication could retrieve this information, leading to privacy breaches and potential misuse of user data.

Compliance Impact

This vulnerability likely violates GDPR and other privacy regulations by exposing personal data without proper access controls. It could result in non-compliance penalties, reputational damage, and loss of user trust due to unauthorized data access.

Mitigation Strategies

Immediately update the ShopApper plugin to the latest version above 0.4.66. If an update is unavailable, consider disabling the plugin temporarily. Review user roles and permissions to ensure least privilege access. Monitor for unauthorized data access attempts in logs.
