Summary

The Formidable Forms plugin for WordPress versions prior to 6.3.1 contains a significant security flaw where it fails to properly authorize users and validate URLs during the installation of add-ons. This vulnerability allows users with minimal roles, such as Subscribers, to install and activate any arbitrary plugins from the WordPress.org repository. This could lead to exploit scenarios including Remote Code Execution, whereby an attacker gains the ability to execute malicious code on the target site.

Affected Version(s)

Exploit Proof of Concept (PoC)
