What is CVE-2026-19220?

The Forminator Forms plugin for WordPress, prior to version 1.57.1, lacks the necessary verification to ensure that site registration is enabled on the network. This oversight allows unauthenticated users to create new sites on a WordPress multisite network, potentially granting them administrator privileges. Such a vulnerability poses significant risks to site security, as it can lead to unauthorized control over the newly created sites.

Affected Version(s)

Forminator Forms 0 < 1.57.1

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.
