CVE-2026-71269 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. 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.. EPSS estimates a 0.59% chance of exploitation in the next 30 days.
