What is CVE-2026-87069?

The Forminator Forms WordPress plugin prior to version 1.57.2.1 contains a significant security flaw that allows authenticated users, including those with minimal permissions (like Subscribers), to alter the saved configurations of forms, including payment forms. This issue arises from the absence of adequate checks—specifically nonce, capability, and ownership verifications—during the migration of one-time payment fields on admin screens. Consequently, any logged-in user can execute unauthorized changes, leading to potential security risks on websites utilizing this plugin.

Affected Version(s)

Forminator Forms 1.38.1 < 1.57.2.1

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.
