Name of the Vulnerable Software and Affected Versions MStore API plugin for WordPress versions up to, and including, 3.9.0

Description The issue is related to authentication bypass due to insufficient verification of the user during the coupon redemption REST API request. This allows unauthenticated attackers to log in as any existing user, including administrators, if they have access to the user id.

Recommendations For MStore API plugin for WordPress versions up to, and including, 3.9.0, update to a version higher than 3.9.0 to resolve the issue. As a temporary workaround, consider restricting access to the coupon redemption REST API endpoint to minimize the risk of exploitation. Avoid using the user id in the affected API endpoint until the issue is resolved.
