Vulnerability Title
Kirki <= 6.1.1 - Missing Authorization to Authenticated (Subscriber+) Sensitive Information Disclosure via 'context' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.1.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with custom-level access and above, to read arbitrary user metadata and sensitive user record fields — including email address, assigned roles, registration date, and any user_meta values — belonging to any WordPress user including administrators, by supplying a target user ID with a user-type context to the frontend collection endpoint.
