What is CVE-2026-108066?
CVE-2026-108066 is a low-severity missing authorization vulnerability in Unknown WP 2FA, published on 14 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
The WP 2FA WordPress plugin before 4.2.0 does not perform an object-level capability check before removing a user's two-factor authentication configuration, allowing a site administrator on WordPress Multisite to remove the 2FA configuration of users outside their own site, including accounts they are not permitted to edit. On single-site installs an administrator can already manage all users, so this crosses a trust boundary only on Multisite.
Weakness: CWE-639
