Description

OpenClaw has hook auth rate limiter bypass via IPv4-mapped IPv6 client key variants

Vulnerability

The hook authentication throttle keyed failed attempts by raw socket remoteAddress text.

IPv4 and IPv4-mapped IPv6 forms of the same client (for example 1.2.3.4 and ::ffff:1.2.3.4) were treated as different clients, allowing separate rate-limit buckets.

Impact

An attacker could split failed hook-auth attempts across both address forms and effectively double the brute-force budget from 20 to 40 attempts per 60-second window.

Affected Components

  • src/gateway/server-http.ts
  • src/gateway/auth-rate-limit.ts

Affected Packages / Versions

  • Package: openclaw (npm)
  • Vulnerable versions: <= 2026.2.21-2
  • Patched version (planned next release): 2026.2.22

Remediation

Centralize and reuse canonical client-IP normalization for auth rate-limiting, and use that canonical key for hook auth throttling.
