What is CVE-2026-19221?

The Forminator Forms plugin for WordPress, prior to version 1.57.0.5, exposes a critical weakness that allows any site administrator within a multisite network to execute arbitrary code. This occurs due to the improper restriction of a network-wide setting, thereby enabling potential malicious actions across the entire network. Site admins should immediately consider updating their plugin version to mitigate this risk.

Affected Version(s)

Forminator Forms 1.40.0 < 1.57.0.5

Exploit Proof of Concept (PoC)
