Guide for securing API endpoints with proper input validation, path traversal prevention, and parameter sanitization. Auto-invoked when working on route handlers or API endpoints.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# API Security — Input Validation & Path Safety All input validation and path security functions live in **`server/utils/pathSecurity.js`**. Never write inline validation — always use these centralized utilities. ## Function Reference ### ID Validation | Function | Signature | Use When | |----------|-----------|----------| | `isValidId` | `(id) → boolean` | Checking any user-supplied ID (app, model, source, tool, prompt, page, renderer, skill, group, provider, client) | | `validateIdForPath` | `(id, idType, res?) → boolean` | Express handler — sends 400 and returns `false` on invalid. Pass `res` to auto-respond | | `validateIdsForPath` | `(ids, idType, res) → string[] \| false` | Batch validation. Accepts comma-separated string, array, or `'*'` wildcard | ### Language Code Validation | Function | Signature | Use When | |----------|-----------|----------| | `isValidLanguageCode` | `(lang) → boolean` | Validating BCP-47 codes like `en`, `de`, `en-US`, `pt-BR` | | `sanitizeLanguageCode` | `(lang, fallback?) → string` | Coercing a query param to a safe language code (defaults to `'en'`) | …

How to install
mdr add intrafind/ihub-apps/api-security@sha256:2372a3e645b0fb13The line at the top of this page pins the label git:20260224.14571f2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
