What is CVE-2026-100143?

The FluentCart plugin for WordPress prior to version 1.6.5 exhibits a security weakness in its guest checkout functionality. Specifically, it fails to validate control over the email address used during the guest checkout process. This oversight allows malicious users who are aware of an existing guest customer's email to gain unauthorized access to a logged-in account associated with that email, compromising the customer's stored data and personal information.

Affected Version(s)

FluentCart A New Era of eCommerce 0 < 1.6.5

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.
