What is CVE-2026-86851?

The Livees Checkout WordPress plugin (up to version 7.0.2) suffers from a serious security flaw where it fails to validate user permissions, nonce tokens, or order keys on the order confirmation page. This lack of security checks enables unauthenticated attackers to change the status of any order, insert arbitrary data and notes, and retrieve sensitive order keys, posing a significant risk to e-commerce operations and customer data integrity.

Affected Version(s)

Livees Checkout 6.8 <= 7.0.2

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.
