Each rust dot is a disclosed event in this advisory's life: when it was published, when (if ever) a patch shipped, when exploitation was observed in the wild, and where things stand today (the dashed line). Ghosted dots are events that haven't happened yet.

Summary

OpenClaw's local dashboard accepts WebSocket connections without validating the Origin header. Any web page visited while OpenClaw is running can open the WebSocket and trigger tool execution. With default tools enabled, this is a full RCE.

What to do

  • If you run an affected version: upgrade to 2026.2.10 immediately. Do not delay this for convenience reasons.
  • Rotate any credentials that may have been exposed via the affected component.
  • Audit your logs for indicators of exploitation — unexpected outbound traffic, anomalous tool calls, unfamiliar authenticated sessions.
  • If exploitation is confirmed, treat the host as compromised: rebuild from a clean image, rotate every secret on the host, audit lateral movement.
