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.
