SCA: security update for magicmirror (GHSA-q4gh-4ffp-5cg8)

medium Tenable Self-Hosted Container Security Plugin ID 446055

Description

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

 - MagicMirror² is an open source modular smart mirror platform. Prior to 2.37.0, when hideConfigSecrets is
 enabled, the catch-all socket dispatcher in js/node_helper.js passes every inbound object payload through
 replaceSecretPlaceholder in js/server_functions.js before invoking socketNotificationReceived. A client
 connected to a loaded module namespace can submit a SECRET_API_KEY placeholder, causing the server to
 replace it with the corresponding process environment value. The default weather helper accepts
 INIT_WEATHER, copies the attacker-controlled instanceId, and returns it in WEATHER_ERROR, providing an
 echo path for the expanded secret. This reverses the intended one-way redaction boundary and can disclose
 API tokens, credentials, or service keys stored in SECRET_ variables. This issue is fixed in version
 2.37.0. (CVE-2026-63640)

Solution

Update the magicmirror library and its related packages to version 2.37.0 or later.
