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&#8217;s &#8220;Restore&#8221; 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.<\/p>\n<p>Severity: 0.0 | NA<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-66398 Published : Jan. 1, 2026, 6 p.m. | 24\u00a0minutes ago Description : Signal K Server is a server application that runs on a central hub in a boat.
