rConfig Core 8.0.0 before 8.2.10 contains an authentication bypass vulnerability that allows unauthenticated attackers to self-register accounts with full Administrator privileges due to a duplicate bare Auth::routes() call in routes/web.php that re-enables the POST /register route after it was explicitly disabled. Attackers can register a new account that is immediately authenticated with Admin-level access because the registration controller does not assign a role and the users.role column defaults to Admin, enabling access to stored device credentials, user data, and API token issuance.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
