high Tenable Self-Hosted Container Security Plugin ID 438353

Description

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

 - WARNING: Users of 6.x should upgrade to 6.2.4 or later as the fix was missed in previous 6.x releases. See
 the following for more details: https://activemq.apache.org/security-
 advisories.data/CVE-2026-40046-announcement.txt https://www.cve.org/CVERecord?id=CVE-2026-40046 Original
 Report: Apache ActiveMQ does not properly validate the remaining length field which may lead to an
 overflow during the decoding of malformed packets. When this integer overflow occurs, ActiveMQ may
 incorrectly compute the total Remaining Length and subsequently misinterpret the payload as multiple MQTT
 control packets which makes the broker susceptible to unexpected behavior when interacting with non-
 compliant clients. This behavior violates the MQTT v3.1.1 specification, which restricts Remaining Length
 to a maximum of 4 bytes. The scenario occurs on established connections after the authentication process.
 Brokers that are not enabling mqtt transport connectors are not impacted. This issue affects Apache
 ActiveMQ: before 5.19.2, 6.0.0 to 6.1.8, and 6.2.0 Users are recommended to upgrade to version 5.19.2,
 6.1.9, or 6.2.1, which fixes the issue. (CVE-2025-66168)

Solution

Update the org.apache.activemq:activemq-all library and its related packages to version 5.19.2 or later.
