Description

OpenClaw: Gateway HTTP endpoints re-resolve bearer auth after SecretRef rotation

Summary

Gateway HTTP and WebSocket handlers captured the resolved bearer-auth configuration when the server started. After a SecretRef rotation, the already-running gateway could continue accepting the old bearer token until restart.

Impact

A bearer token that should have been revoked by SecretRef rotation could remain valid on the gateway HTTP and upgrade surfaces for the lifetime of the process. Severity remains high because the old token could continue to authorize gateway requests after operators believed it was rotated out.

Affected versions

  • Affected: < 2026.4.15
  • Patched: 2026.4.15

Fix

OpenClaw 2026.4.15 resolves active gateway auth from the runtime secret snapshot per request and per upgrade instead of using a stale startup-time value.

Verified in v2026.4.15:

  • src/gateway/server.impl.ts exposes getResolvedAuth() backed by the current runtime secret snapshot.
  • src/gateway/server-http.ts calls getResolvedAuth() for each HTTP request and WebSocket upgrade before running auth checks.
  • src/gateway/server-http.probe.test.ts verifies /ready re-resolves bearer auth after rotation and rejects the old token.

Fix commit included in v2026.4.15 and absent from v2026.4.14:

  • acd4e0a32f12e1ad85f3130f63b42443ce90f094 via PR #66651

CVSS metrics in full

The score comes from this vector: CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Attack requirements: Present — the target has to be in a particular state for the attack to work.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
