HighCVSS 7.5

Exploitation Probability (EPSS)

Low risk
0.14%

3th percentile - higher than 3% of all known CVEs

Summary

The PhonePe Payment Solutions WordPress plugin before version 3.1.0 does not properly verify the authenticity of incoming payment callbacks. The secret used to validate the callback signature is empty on sites configured through the current setup flow, so the expected signature reduces to an unkeyed hash of the request body that anyone can compute. This allows unauthenticated attackers to forge a payment-success notification and mark unpaid WooCommerce orders as paid without any payment being made.

Risk Assessment

The organization is exposed to financial loss and order manipulation – an attacker can mark any order as paid without actual payment, leading to shipment of goods without receiving funds.

Recommendation

Immediately update the PhonePe Payment Solutions plugin to version 3.1.0 or later. After updating, verify that the callback secret is properly configured and not empty.
