SCA: security update for signalk-server (GHSA-w3x5-7c4c-66p9)

high Tenable Cloud Security Plugin ID 436548

Description

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

 - Signal K Server is a server application that runs on a central hub in a boat. 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.
 (CVE-2025-66398)

Solution

Update the signalk-server library and its related packages to version 2.19.0 or later.
