SCA: security update for signalk-server (GHSA-vrhw-v2hw-jffx)

medium Tenable Self-Hosted Container Security Plugin ID 437422

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 2.20.3, a path
 traversal vulnerability in SignalK Server's applicationData API allows authenticated users on Windows
 systems to read, write, and list arbitrary files and directories on the filesystem. The validateAppId()
 function blocks forward slashes (/) but not backslashes (\), which are treated as directory separators by
 path.join() on Windows. This enables attackers to escape the intended applicationData directory. This
 vulnerability is fixed in 2.20.3. (CVE-2026-25228)
