What is CVE-2026-121633?

The Order Tracking Plugin for WordPress allows unauthenticated users to mark orders as paid without proper verification. Versions before 3.6.0 do not ensure that a PayPal payment notification corresponds with the merchant's account or matches the total order amount. This security flaw can be exploited by malicious actors to falsely mark orders as paid by sending trivial payments to their own PayPal accounts, posing significant risks to e-commerce sites using this plugin.

Affected Version(s)

Order Tracking 0 < 3.6.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
