### 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. ### Fix Commit(s) - `8f3310000a8b0c11eced054c2cdb6fb27803511a` ### Release Process Note `patched_versions` is pre-set to the release (`2026.2.25`). Advisory published with npm release `2026.2.25`.2.25` is published, this advisory is published. OpenClaw thanks @zdi-disclosures for reporting.
