What is CVE-2026-81428?

The WC Vendors plugin for WordPress, prior to version 2.7.2.1, contains a critical oversight that allows authenticated users with vendor roles to manipulate product variations that do not belong to them. By exploiting this flaw, these users can alter the status and title of various posts and products, as the plugin fails to correctly validate the ownership or type of user-supplied IDs when saving product variations. This vulnerability highlights a significant risk of unauthorized changes in a multi-vendor setup.

Affected Version(s)

WC Vendors 0 < 2.7.2.1

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.
