-------- DESCRIPTION ---------------------------------------------------------
The Registration Codes module enables site administrators to restrict registration for new accounts to only users who provide a valid registration code.
The default module installation provides no access check for the registration code list, leading to a vulnerability that allows unauthenticated members to easily view the registration code list.
-------- VERSIONS AFFECTED ---------------------------------------------------

Drupal core is not affected. If you do not use the contributed Registration Codes [1] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------
