Forminator Forms <= 1.57.2.0 - Missing Authorization to Unauthenticated Arbitrary Post Meta Injection
The Forminator Forms plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 1.57.2.0. This is due to missing allowlist validation on meta keys supplied by form submissions, which allowed arbitrary and protected meta keys to be written without restriction. This makes it possible for unauthenticated attackers to inject arbitrary post metadata—including WordPress-reserved protected keys—into posts created by form submissions, potentially altering post behaviour or bypassing application logic.
