Tokens issued to a low-privileged user are not sufficiently restricted, allowing them to be used to access product-level Admin REST APIs.

Exploitation of this vulnerability allows a low-privileged user to invoke the Admin REST APIs of WSO2 products, potentially leading to full administrative account takeover. This requires the attacker to already possess a low-privileged user account and be able to obtain a valid token for it.
