Prior to version 2.19.0, an unauthenticated attacker can pollute the internal state (`restoreFilePath`) of the server via the `/skServer/validateBackup` endpoint. This allows the attacker to hijack the administrator's \"Restore\" functionality to overwrite critical server configuration files (e.g., `security.json`, `package.json`), leading to account takeover and Remote Code Execution (RCE). Version 2.19.0 patches this vulnerability.","state":0,"publishedAt":"2026-01-01T18:15:40.55+00:00","modifiedAt":"2026-10-07T11:10:00.153+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6,"severity":"CRITICAL"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/SignalK/signalk-server/releases/tag/v2.19.0","https://github.com/SignalK/signalk-server/security/advisories/GHSA-w3x5-7c4c-66p9"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-66398","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-78","CWE-913"],"productCriteria":["cpe:2.3:a:signalk:signal_k_server:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-01-01T18:15:40.550","lastModified":"2026-10-07T11:10:00.153"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
