A remote unauthenticated attacker could send oversized payloads and cause memory pressure, degrading availability.</p> <p>### Details Affected packages: - `openclaw` (npm): `&lt;2026.2.12` - `clawdbot` (npm): `&lt;=2026.1.24-3`</p> <p>Root cause: - Webhook code paths buffered request payloads without consistent `maxBytes` + `timeoutMs` enforcement. - Some SDK-backed handlers parse request bodies internally and needed stream-level guards.</p> <p>Attack shape: - Send very large JSON payloads or slow/incomplete uploads to webhook endpoints. - Observe elevated memory usage and request handler pressure.</p> <p>### Impact Remote unauthenticated availability impact (DoS) via request body amplification/memory pressure.</p> <p>### Patch details (implemented) - Added shared bounded request-body helper in `src/infra/http-body.ts`. - Exported helper in `src/plugin-sdk/index.ts` for extension reuse. - Migrated webhook body readers to shared helper for: - LINE - Nextcloud Talk - Google Chat - Zalo - BlueBubbles - Nostr profile HTTP - Voice-call - Gateway hooks - Added stream guards for SDK handlers that parse request bodies internally: - Slack - Telegram - Feishu - Added explicit Express JSON body limit handling for MS Teams webhook path. - Standardized failure responses: - `413 Payload Too Large` - `408 Request Timeout`</p> <p>### Tests - Added regression tests: - `src/infra/http-body.t…</p> <p><strong>Affected:</strong> Homebrew: openclaw-cli</p> <p>### Summary Multiple webhook handlers accepted and buffered request bodies without a strict unified byte/time limit.
