  "details": "## Vulnerability\n\nThe hook authentication throttle keyed failed attempts by raw socket `remoteAddress` text.\n\nIPv4 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.\n\n## Impact\n\nAn 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.\n\n## Affected Components\n\n- `src/gateway/server-http.ts`\n- `src/gateway/auth-rate-limit.ts`\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Vulnerable versions: `\u003c= 2026.2.21-2`\n- Patched version (planned next release): `2026.2.22`\n\n## Remediation\n\nCentralize and reuse canonical client-IP normalization for auth rate-limiting, and use that canonical key for hook auth throttling.\n\n## Fix Commit(s)\n\n- `3284d2eb227e7b6536d543bcf5c3e320bc9d13c5`\n\n## Release Process Note\n\n`patched_versions` is pre-set to the planned next release (`2026.2.22`) so once npm release `2026.2.22` is published, this advisory can be published directly.\n\nOpenClaw thanks @aether-ai-agent for reporting.",
