OpenClaw ClawJacked: 135,000 Exposed AI Agent Instances Vulnerable to Silent WebSocket Localhost Hijack
Oasis Security·medium signal
Oasis Security found that OpenClaw's local WebSocket gateway exempts localhost from rate limiting, allowing any website to brute-force the gateway password at hundreds of attempts per second and silently register as a trusted device — no user interaction required. With 135,000 publicly exposed instances and 138 CVEs discovered in 63 days (2.2 per day), OpenClaw exemplifies the 'implicit localhost trust' anti-pattern. Builders running local AI agents should audit whether their WebSocket gateways properly authenticate localhost connections.
