AI risk analysis

Summary: The flaw allows an attacker to traverse directories and potentially execute arbitrary code by manipulating path parameters in Node-RED's local-filesystem library storage module.
Exploitability: Exploitation requires access to the web interface and control over the path parameter, making it moderately difficult but feasible with proper conditions.
Blast radius: If exploited, this could lead to full compromise of the affected system, including data theft or execution of malicious code.
Prioritized remediation: Update Node-RED to a version that addresses this vulnerability or disable the affected library module.

NVD description

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.
