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":"2026-01-01T18:00:38.575+00:00","modifiedAt":"2026-01-05T21:00:41.972+00:00","affected":[{"ecosystem":"Vendor product","name":"signalk-server","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"SignalK\",\n                    \"product\": \"signalk-server\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.19.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.7,"severity":"CRITICAL"}],"references":["https://github.com/SignalK/signalk-server/security/advisories/GHSA-w3x5-7c4c-66p9","https://github.com/SignalK/signalk-server/releases/tag/v2.19.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-66398","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-66398","identifiers":["CVE-2025-66398"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
