What is CVE-2026-0633?
The MetForm plugin for WordPress is susceptible to a sensitive information exposure that can be exploited by unauthenticated attackers. The vulnerability arises from a forgeable cookie designed using only the entry ID and the current user ID, without any server-side secret for protection. This flaw allows attackers to access confidential form submission data, specifically from entries created within a 15-minute transient TTL, through the MetForm shortcodes.
