Title
Nexting pinclaw through 0.3.0 Missing Authentication via POST /pinclaw/send
Summary
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.
