7.5High

Published 17 Oct 2026 · NVD status: Received · AI triage by gemini-3.8-flash

7.5High

Attack vector: Network
Complexity: Low
Privileges needed: None
User interaction: None
Impact: High impact on confidentiality
Weakness: CWE-639

Impact

Unauthenticated attackers can extract sensitive user profile data and custom user metadata over the network. They only need network access to a published page using a Kirki template with a user-type dynamic content block.

Root cause

Missing validation on the user-controlled 'context' parameter in the REST API handler allows arbitrary user data retrieval.

Affected systems

Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress up to, and including, 6.3.2

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Fix & remediation

Upgrade Kirki to a version newer than 6.3.2. As an interim workaround, unpublish or remove user-type dynamic content blocks from public Kirki templates, or deactivate the plugin.

shell

$ wp plugin update kirki

NVD 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.
