Summary
OpenClaw: Read-scoped identity-bearing HTTP clients could kill sessions via /sessions/:sessionKey/kill
Details

Summary

Before OpenClaw 2026.4.2, POST /sessions/:sessionKey/kill did not enforce write scopes in identity-bearing HTTP modes. A caller limited to read-only operator scopes could still terminate a running subagent session.

Impact

A read-scoped caller could perform a write-class control-plane mutation and interrupt delegated work. This was an authorization bug on the HTTP scope boundary, not a shared-secret compatibility exception.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.4.1
  • Patched versions: >= 2026.4.2

Fix Commit(s)

  • 54a0878517167c6e49900498cf77420dadb74beb — enforce session-kill HTTP scopes

Release Process Note
