Snipe-IT is an IT asset/license management system. Prior to 8.4.1, aAn authenticated user with only users.edit permission can escalate their own privileges to admin by sending a PATCH request to /api/v1/users/{id} with permissions[admin]=1. The API controller only strips the superuser key from the permissions array, allowing admin and all other permission keys to be set by any user who can update users. This vulnerability is fixed in 8.4.1.
