Overview

This vulnerability has a CVSS 3.1 base score of 9.6, rated CRITICAL. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Incorrect Authorization vulnerability in Apache Software Foundation Apache Pulsar.

This issue affects Apache Pulsar: before 2.10.4, and 2.11.0.

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.

The recommended mitigation for impacted users is to upgrade the Pulsar Function Worker to a patched version.

2.10 Pulsar Function Worker users should upgrade to at least 2.10.4.

2.11 Pulsar Function Worker users should upgrade to at least 2.11.1.

3.0 Pulsar Function Worker users are unaffected.

Any users running the Pulsar Function Worker for 2.9.* and earlier should upgrade to one of the above patched versions.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
