SCA: security update for signalk-server (GHSA-93jc-vqqc-vvvh)

high Tenable Self-Hosted Container Security Plugin ID 436543

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. Versions prior to 2.19.0 of
the appstore interface allow administrators to install npm packages through a REST API endpoint. While the
endpoint validates that the package name exists in the npm registry as a known plugin or webapp, the
version parameter accepts arbitrary npm version specifiers including URLs. npm supports installing
packages from git repositories, GitHub shorthand syntax, and HTTP/HTTPS URLs pointing to tarballs. When
npm installs a package, it can automatically execute any `postinstall` script defined in `package.json`,
enabling arbitrary code execution. The vulnerability exists because npm's version specifier syntax is
extremely flexible, and the SignalK code passes the version parameter directly to npm without
sanitization. An attacker with admin access can install a package from an attacker-controlled source
containing a malicious `postinstall` script. Version 2.19.0 contains a patch for the issue.
(CVE-2025-68619)
