FKIE_CVE-2026-8206

Vulnerability from fkie_nvd - Published: 2026-06-02 04:17 - Updated: 2026-06-02 13:03
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions 6.0.0 to 6.0.6. This is due to the plugin accepting an arbitrary email address when a username is used in the password reset request. This makes it possible for unauthenticated attackers to send a password reset link for any user registered on the site to their own email address.
