Short explanation

Nexting pinclaw OpenClaw channel plugin through version 0.3.0 contains a vulnerability that skips authentication checks on the POST /pinclaw/send endpoint.

Why does it matter?

Unauthenticated attackers with network access can inject blind prompts directly into the user's main OpenClaw agent session as user instructions.

What should be done?

  • Follow official vendor advisories for updates
  • Apply vendor patches as patch status is currently UNKNOWN
  • Restrict network access to port 18790
