ClawJacked Flaw Could Let Malicious Sites Take Over Local OpenClaw AI Agents

· Original article ↗

Summary

OpenClaw patched ClawJacked in version 2026.2.25. Oasis Security said malicious websites could exploit the local gateway’s password and device-registration weaknesses to gain control of an agent. The article also details malicious skills and recommends updates and safer

Key points

  • Oasis Security reported that JavaScript on an attacker-controlled website could connect to a local OpenClaw gateway over WebSocket and brute-force its password because rate limiting was missing.
  • After authentication, the attacker could register as a trusted device without user approval and gain control of the agent, including access to configurations, connected nodes, and logs.
  • OpenClaw released a ClawJacked fix in version 2026.2.25 on February 26, 2026; the article advises users to update and audit agent access.
  • A separate log-poisoning issue, which could enable indirect prompt injection through logs read by the agent, was fixed in version 2026.2.13.
  • The article reports malicious ClawHub skills delivering Atomic Stealer and cryptocurrency scams, including skills that direct agents to expose wallet keys or route payments to attacker-controlled infrastructure.
  • Microsoft advised evaluating OpenClaw only in an isolated environment with dedicated, non-privileged credentials and access to non-sensitive data; users are also advised to vet skills and monitor their behavior.
