Unauthenticated file disclosure via assets path traversal
Published Aug 11, 2023 · Updated Oct 9, 2024
Path traversal in Foddy node-red-contrib-huemagic 3.0.0 allows remote attackers to read server files through the Hue assets endpoint. The /hue/assets/:file route passes req.params.file into path.resolve and res.sendFile without restricting the resolved path to the previews directory. The route lacks a Node-RED permission check, so an unauthenticated crafted path can disclose any file readable by the Node-RED process.
