CVE-2026-41298
OpenClaw: Read-scoped identity-bearing HTTP clients could kill sessions via /sessions/:sessionKey/kill
Description
## 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. Thanks @EaEa0001 for reporting.
