  "details": "### Summary\n\nThe affected surface is the OpenClaw macOS app onboarding flow, and the macOS app is currently in **beta**.\nIn that beta onboarding flow, Anthropic OAuth used the PKCE `code_verifier` value as OAuth `state`, exposing that secret in front-channel URL state.\n\n### Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected versions: `\u003c= 2026.2.24` (latest published npm at triage time)\n- Affected surface: macOS app beta onboarding path (`apps/macos`)\n- Not affected: core CLI/gateway onboarding paths\n- Patched version : `2026.2.25`\n\n### Impact\n\nScope is limited to the macOS beta onboarding OAuth path. Exploitation required obtaining both OAuth authorization artifacts and exposed `state` values during that flow.\n\n### Remediation\n\nOpenClaw removed Anthropic OAuth sign-in from macOS onboarding and now supports setup-token-only Anthropic subscription auth in this path.\n\n### Fix Commit(s)\n\n- `8f3310000a8b0c11eced054c2cdb6fb27803511a`\n\n### Release Process Note\n\n`patched_versions` is pre-set to the release (`2026.2.25`).\nAdvisory published with npm release `2026.2.25`.2.25` is published, this advisory is published.\n\nOpenClaw thanks @zdi-disclosures for reporting.",
