Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. When a client connects to the Pulsar Function Worker via the Pulsar Proxy where the Pulsar Proxy uses mTLS authentication to authenticate with the Pulsar Function Worker, the Pulsar Function Worker incorrectly performs authorization by using the Proxy's role for authorization instead of the client's role, which can lead to privilege escalation, especially if the proxy is configured with a superuser role.
