Vulnerability from fkie_nvd - Published: 2026-01-24 09:15 - Updated: 2026-04-15 00:35
Severity ?
3.7 (Low) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N
Summary
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).
