Password confirmation stored in plain text via registration form in statamic/cms

Users registering via the user:register_form tag will have their password confirmation stored in plain text in their user file.

Impact

This only affects sites matching all of the following conditions:

• Running Statamic versions between 5.3.0 and 5.6.1. (This version range represents only one calendar week)
• Using the user:register_form tag.
• Using file-based user accounts. (Does not affect users stored in a database.)
• Has users that have registered during that time period. (Existing users are not affected.)

The password is only visible to users that have access to read user yaml files, typically developers of the application itself.

Patches

The issue has been patched in 5.6.2, however any users registered during that time period and using the affected version range will still have the the password_confirmation value in their yaml files.

We recommend that affected users have their password reset. The following query can be entered into php artisan tinker and will output a list of affected emails:

Statamic\Facades\User::query()->whereNotNull('password_confirmation')->get()->map->email

The following can be entered into tinker and will clear both password_confirmation as well as their existing password. They will be required to reset their password before their next login attempt.

Statamic\Facades\User::query()
  ->whereNotNull('password_confirmation')->get()
  ->each(fn ($user) => $user->remove('password_confirmation')->passwordHash(null)->save());

If you are committing user files to a public git repo, you may consider clearing the sensitive data from the git history. You can use the following links for details.
