Summary

A path traversal vulnerability in Node-RED's local-filesystem library storage module (getLibraryEntry and saveLibraryEntry in packages/node_modules/@node-red/runtime/lib/storage/localfilesystem/library.js), reachable via GET/POST /library/:lib/:type/*path, joins the user-supplied path parameter directly into the filesystem path via fspath.join(libDir, type, path) with no traversal sanitization, containment check, or path normalization/prefix verification.

Risk Assessment

An attacker could access or modify arbitrary files on the server, potentially leading to data leakage or system compromise.

Recommendation

Upgrade Node-RED to a patched version or apply access restrictions to the /library endpoint.
