What is CVE-2026-86816?

The WPCafe WordPress plugin prior to version 3.0.21 has a significant flaw in its REST API, where it fails to adequately restrict access to certain endpoints. This oversight allows unauthenticated users to infiltrate sensitive areas of the site, thereby gaining access to critical WooCommerce product data, which includes detailed sales counts, precise stock levels, and confidential product metadata that would typically require proper authentication to view.

Affected Version(s)

WPCafe 0 < 3.0.21

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.
