Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Unauthenticated remote attackers could manipulate request paths/URLs to bypass Express middleware checks and access sensitive administrative, flow, and editor routes within the Node-RED plugin, leading to remote code execution.
Path Traversal: The lack of file-path canonicalization and sanitization allowed authenticated and unauthenticated users to use directory traversal sequences inside file upload and writing functions to write arbitrary files outside the sandboxed projects directory.
Hardcoded Credentials: The system used a hardcoded default secret key to sign and verify JWT administrative tokens, enabling unauthenticated remote attackers to forge valid administrative tokens.
