## What is CVE-2026-107762?

CVE-2026-107762 is a high-severity vulnerability in themeum Kirki – Freeform Page Builder, Website Builder & Customizer, published on 17 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.3.2 via the 'context' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to expose arbitrary users' sensitive profile data — including email address, display name, nicename, registration date, profile image URL, and any string-valued user meta fields such as first name, last name, nickname, description, and custom meta keys — via the REST response. Exploitation requires a published page that uses a Kirki template containing at least one user-type dynamic content block; target user IDs are enumerable via standard WordPress REST endpoints, making the only prerequisite the presence of such a template on the site.

Weakness: CWE-639 (Authorization Bypass Through User-Controlled Key)
