What the vulnerability does
01Description
The MetForm – Contact Form, Survey, Quiz, & Custom Form Builder for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 4.1.0. This is due to the use of a forgeable cookie value derived only from the entry ID and current user ID without a server-side secret. This makes it possible for unauthenticated attackers to access form submission entry data via MetForm shortcodes for entries created within the transient TTL (default is 15 minutes).
Explanation of Vulnerability in Simple Terms
02Summary
MetForm versions up to 4.1.0 contain an authentication weakness that allows an attacker to gain limited access to sensitive information. The vulnerability requires specific network conditions to exploit but does not require user interaction or authentication. The flaw affects the form builder's authentication mechanism, potentially exposing data confidentiality.
