# Craft CMS: public registrants can reclaim deactivated accounts with their old permissions

Link for people: https://infrastack.ai/live/CVE-2026-124429 (this .md is for agents)

Craft CMS from 5.0.0 before 5.11.2 lets an unauthenticated visitor register and reclaim a deactivated non-admin account. The reclaimed account keeps its stored direct permissions, so an attacker can take over a privileged account when email verification is disabled.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Craft CMS version in `composer.json` or `composer show craftcms/cms`; versions from `5.0.0` up to but not including `5.11.2` are in the affected range.
- Check whether email verification for public registration is turned off in the Craft control panel user settings.
- Look for deactivated user accounts that still hold direct permissions in the `userpermissions_users` table.

## Fix

- Craft CMS: move to `5.11.2` or later.

## From the sources

Craft CMS from 5.0.0 before 5.11.2 contains a privilege escalation vulnerability that allows unauthenticated public registrants to reclaim deactivated non-admin accounts while retaining their direct permissions. Attackers can register using a deactivated account, set a new password, and inherit permissions stored in userpermissions_users, enabling privileged account takeover when email verification is disabled.
