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.","state":0,"publishedAt":"2026-08-18T18:19:11.8+00:00","modifiedAt":"2026-10-22T22:10:00.25+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":4.3,"severity":"MEDIUM"}],"references":["https://github.com/MagicMirrorOrg/MagicMirror/commit/ca7b752025962441196e148f8c1bc04b90117979","https://github.com/MagicMirrorOrg/MagicMirror/pull/4184","https://github.com/MagicMirrorOrg/MagicMirror/releases/tag/v2.37.0","https://github.com/MagicMirrorOrg/MagicMirror/security/advisories/GHSA-q4gh-4ffp-5cg8"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-63640","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-200"],"productCriteria":[],"sourceDates":{"published":"2026-08-18T18:19:11.800","lastModified":"2026-10-22T22:10:00.250"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
