Who should care

Defenders responsible for WordPress installations with the Sifalo Pay plugin should assess exposure and prioritize verification and remediation efforts. This includes reviewing and adjusting plugin configurations, monitoring for suspicious payment activity, and implementing additional security measures as needed. Security teams and vulnerability management teams should also be aware of the potential impact and take necessary actions to protect their assets

Why it matters

CVE-2026-94261 allows unauthenticated attackers to mark arbitrary pending orders as paid in the Sifalo Pay WordPress plugin before 2.5.3, potentially leading to financial losses. Defenders should prioritize verification and remediation.

• Unauthenticated attackers can mark arbitrary pending orders as paid, potentially leading to financial losses
• Defenders need to verify the affected Sifalo Pay plugin versions and ensure proper configuration to prevent unauthorized payment confirmation
• Additional security measures may be necessary to monitor for suspicious payment activity

Technical summary

The Sifalo Pay WordPress plugin before 2.5.3 does not verify that a payment transaction identifier belongs to the order it is confirming, nor that the requester owns that order. This allows unauthenticated attackers holding one valid transaction identifier from a payment of their own to mark arbitrary pending orders as paid. The vulnerability could lead to financial losses if exploited. The issue arises from a lack of proper validation and authorization in the payment confirmation process. Defenders should prioritize verifying the affected Sifalo Pay plugin versions and ensuring proper configuration to prevent unauthorized payment confirmation.
