Name of the Vulnerable Software and Affected Versions Apache Pulsar versions prior to 2.10.4 Apache Pulsar version 2.11.0

Description The issue affects Apache Pulsar when a client connects to the Pulsar Function Worker via the Pulsar Proxy, which uses mTLS authentication. The Pulsar Function Worker incorrectly performs authorization by using the Proxy's role instead of the client's role, leading to potential privilege escalation, especially if the proxy is configured with a superuser role.

Recommendations For Apache Pulsar version 2.10, upgrade to at least version 2.10.4. For Apache Pulsar version 2.11, upgrade to at least version 2.11.1. For Apache Pulsar versions 2.9 and earlier, upgrade to one of the above patched versions.
