SB2026032460 - Incorrect authorization in Apache Artemis

Description

This security bulletin contains information about 1 security vulnerability.

1) Incorrect authorization (CVE-ID: CVE-2026-32642)

The vulnerability allows a local user to bypass authorization and create a temporary address without proper permissions.

The vulnerability exists due to incorrect authorization in the OpenWire protocol component when handling non-durable JMS topic subscription creation on a non-existent address. A local user can exploit improper permission checks during subscription creation to bypass authorization and cause the unintended creation of a temporary address.

Exploitation requires the user to have the 'createDurableQueue' permission but not the 'createAddress' permission, with address auto-creation disabled.

Remediation

Install update from vendor's website.
