Technical Summary

The PayHere Payment Gateway Plugin for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to an improper validation logic in the check_payhere_response function in all versions up to, and including, 2.3.9. This makes it possible for unauthenticated attackers to change the status of pending WooCommerce orders to paid/completed/on hold.

Potential Impact

Severity is MEDIUM (CVSS 5.3). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as High based on remote code execution potential, low-bar exploit prerequisites.

Primary risk drivers: remote code execution potential, low-bar exploit prerequisites

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
