## 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` - Latest published npm version: `2026.4.1`

## Fix Commit(s)

- `54a0878517167c6e49900498cf77420dadb74beb` — enforce session-kill HTTP scopes

## Release Process Note

The fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live.
