CVE-2026-124429 · Severity: high · CVSS 7.5 · Published 2026-11-08

Craft CMS is a content management system used to build and manage websites. An unauthenticated attacker can register on sites with public registration enabled, reclaim a deactivated account, and gain all the permissions that account previously had—allowing takeover of privileged accounts. This is especially dangerous when email verification is disabled.

## How to fix

- Fixed in 5.11.2

## Technical details

The vulnerability is a privilege escalation in Craft CMS versions 5.0.0 through 5.11.1 affecting the public registration flow. When an attacker registers with a deactivated account username, the system reactivates the account under the new password but fails to clear the direct permissions stored in the userpermissions_users table, which were retained from the original account. Exploitation requires public registration to be enabled and is trivial if email verification is disabled.

## Affected products

- Craft CMS 5.0.0 before 5.11.2
