SCA: security update for io.moquette:moquette-broker (GHSA-5f42-97gr-vfhq)

critical Tenable Cloud Security Plugin ID 476211

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Moquette is a lightweight Java MQTT broker. Prior to 0.18.1, when pattern-based ACL rules are configured,
AuthorizationsCollector.canDoOperation substitutes client ID and username values directly into rules
containing %c or %u and then treats the result as an MQTT topic filter. A client that uses + or # in
either identity can broaden the substituted filter and gain cross-tenant read and write access. A #
identity can also produce an invalid filter that triggers a NullPointerException in Topic.match and
disrupts session processing. This issue is fixed in version 0.18.1. (CVE-2026-85724)

Solution

Update the io.moquette:moquette-broker library and its related packages to version 0.18.1 or later.
