8.3 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:H
CWE
  • CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
OpenHop is a tool for creating interactive data-flow diagrams. Prior to 0.3.7, `@openhop/server` passes unauthenticated flow route parameters from `GET /api/flows/:id` and `DELETE /api/flows/:id` in `packages/server/src/routes.ts` to `FlowStore.filePath()` in `packages/server/src/store.ts` without an identifier allow-list. The router applies `decodeURIComponent` to the id, and `path.join()` then normalizes traversal outside the configured flow directory after appending the .yaml extension. An attacker can read accessible YAML files as YAML-parsed JSON or permanently delete accessible .yaml files outside that directory, exposing configuration or secrets and disrupting dependent services. In `packages/server/src/index.ts`, CORS `origin: true` permits any browser origin, enabling a malicious webpage to target a loopback-bound instance. Docker deployments default to `HOST=0.0.0.0` and permit direct unauthenticated network access. This issue is fixed in repository release 0.3.7.
