NVD description
Nexting pinclaw OpenClaw channel plugin through 0.3.0 contains a missing authentication vulnerability in src/core/http-router.ts that skips the authToken check on POST /pinclaw/send. Unauthenticated attackers reaching port 18790, which binds all interfaces by default, can inject blind prompts into the user's main OpenClaw agent session as user instructions.
What to do
- NVD lists no fixed version yet: follow the vendor advisory below and keep OpenClaw off the public internet until a fix ships.
- Do not expose the component's API or UI to the internet without authentication in front of it.
