Description

Summary

The manual Chutes OAuth login flow could accept attacker-controlled callback input in a way that bypassed OAuth CSRF state validation, potentially resulting in credential substitution.

Impact

If an attacker can convince a user to paste attacker-provided OAuth callback data during the manual login prompt, OpenClaw may exchange an attacker-obtained authorization code and persist tokens for the wrong Chutes account.

The automatic local callback flow is not affected (it validates state in the local HTTP callback handler).

Affected Packages / Versions

  • openclaw (npm): <= 2026.2.13 when using the manual Chutes OAuth login flow.

Fix

The manual flow now requires the full redirect URL (must include code and state), validates the returned state against the expected value, and rejects code-only pastes.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.2.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7rcp-mxpq-72pj is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
