What is CVE-2026-12973?

The PayPlus Payment Gateway plugin for WordPress has a security flaw that allows unauthenticated users to exploit AJAX actions, leading to unauthorized access to sensitive WooCommerce order information. By bypassing necessary authorization and order-ownership checks, attackers could potentially reveal secret keys associated with arbitrary orders and, in certain configurations, manipulate order statuses. This poses significant risks to the integrity of e-commerce transactions.

Affected Version(s)

PayPlus Payment Gateway 0 < 8.2.2

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.
