Summary
OpenClaw Chutes manual OAuth state validation bypass can cause credential substitution
Details

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.

Fix Commit(s)

  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
