## What is CVE-2026-84801?

CVE-2026-84801 is a high-severity authentication bypass vulnerability in craftcms cms, published on 2 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Craft CMS versions before 5.10.11 fail to validate admin status in the actionGetPasswordResetUrl endpoint, allowing non-admin users with administrateUsers permission to mint password reset URLs for administrator accounts. Attackers can generate a valid reset URL for any admin user and set a new password via actionSetPassword, which validates only the verification code without checking the caller's session, enabling complete control-panel takeover.

Weakness: CWE-862 (Missing Authorization)
