AI Analysis
Technical Summary
CVE-2026-12901 is a CWE-345 Insufficient Verification of Data Authenticity vulnerability in the GetPaid WordPress plugin. Versions prior to 2.8.55 do not properly verify the authenticity of incoming Worldpay payment notifications. This allows unauthenticated attackers to forge such notifications, causing the plugin to mark pending invoices as paid without any legitimate payment transaction occurring. The CVSS 3.1 base score is 5.9, reflecting a medium severity with network attack vector, high attack complexity, no privileges required, no user interaction, and impact limited to integrity.
Potential Impact
An attacker can manipulate the payment status of invoices by forging Worldpay payment notifications, potentially causing financial discrepancies by marking invoices as paid without actual payment. This impacts the integrity of the payment processing system but does not affect confidentiality or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider additional verification mechanisms for payment notifications or temporarily disable the affected functionality if feasible.
