OpenClaw: macOS beta onboarding exposed PKCE verifier via OAuth state
Summary
The affected surface is the OpenClaw macOS app onboarding flow, and the macOS app is currently in beta.
In that beta onboarding flow, Anthropic OAuth used the PKCE code_verifier value as OAuth state, exposing that secret in front-channel URL state.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.24(latest published npm at triage time) - Affected surface: macOS app beta onboarding path (
apps/macos) - Not affected: core CLI/gateway onboarding paths
- Patched version :
2026.2.25
Impact
Scope is limited to the macOS beta onboarding OAuth path. Exploitation required obtaining both OAuth authorization artifacts and exposed state values during that flow.
Remediation
OpenClaw removed Anthropic OAuth sign-in from macOS onboarding and now supports setup-token-only Anthropic subscription auth in this path.
