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

  - NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. The nats-
    server provides an MQTT client interface. Prior to versions 2.11.15 and 2.12.5, Sessions and Messages can
    by hijacked via MQTT Client ID malfeasance. Versions 2.11.15 and 2.12.5 patch the issue. No known
    workarounds are available. (CVE-2026-33215)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to
    versions 2.11.15 and 2.12.6, for MQTT deployments using usercodes/passwords: MQTT passwords are
    incorrectly classified as a non-authenticating identity statement (JWT) and exposed via monitoring
    endpoints. Versions 2.11.14 and 2.12.6 contain a fix. As a workaround, ensure monitoring end-points are
    adequately secured. Best practice remains to not expose the monitoring endpoint to the Internet or other
    untrusted network users. (CVE-2026-33216)

  - NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. The nats-
    server provides an MQTT client interface. Prior to versions 2.11.15 and 2.12.5, Sessions and Messages can
    by hijacked via MQTT Client ID malfeasance. Versions 2.11.15 and 2.12.5 patch the issue. No known
    workarounds are available. (CVE-2026-33215)

  - NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to
    versions 2.11.15 and 2.12.6, when using ACLs on message subjects, these ACLs were not applied in the
    `$MQTT.>` namespace, allowing MQTT clients to bypass ACL checks for MQTT subjects. Versions 2.11.15 and
    2.12.6 contain a fix. No known workarounds are available. (CVE-2026-33217)

  - NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to
    versions 2.11.15 and 2.12.6, a client which can connect to the leafnode port can crash the nats-server
    with a certain malformed message pre-authentication. Versions 2.11.15 and 2.12.6 contain a fix. As a
    workaround, disable leafnode support if not needed or restrict network connections to the leafnode port,
    if plausible without compromising the service offered. (CVE-2026-33218)

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - NATS-Server 是適用於雲端與邊緣原生訊息系統 NATS.io 的高效能伺服器。nats-server 提供一個 MQTT 用戶端介面。在 2.11.15 和 2.12.5版之前可以透過 MQTT 用戶端 ID 不當行為劫持工作階段和訊息。2.11.15 和 2.12.5 版包含針對此問題的修補程式。尚無已知的因應措施可以採用。(CVE-2026-33215)

請注意，Nessus 依賴供應商報告的套件存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - NATS-Server 是适用于云和边缘原生消息系统 NATS.io 的高性能服务器。nats-server 提供 MQTT 客户端接口。在低于版本 2.11.15 和 2.12.5的情况下会话和消息可能通过 MQTT 客户端 ID 恶意行为被劫持。2.11.15 和 2.12.5 版本的补丁可解决此问题。没有已知的变通方案可用。(CVE-2026-33215)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
