Snipe-IT is an IT asset/license management system. A vulnerability in versions prior to 8.6.0 allows a non-admin user holding only the granular `users.edit` permission to lock every admin out of the instance by editing the `activated` flag (which determines whether or not a user can login) and the `ldap_import` flag, which determines whether or not the user can request a password reset.
