OpenClaw: Feishu webhook and card-action validation now fail closed
Summary
Feishu webhook mode accepted missing encryptKey configuration as valid and blank card-action callback tokens as usable lifecycle tokens. Together, those fail-open paths could allow unauthenticated webhook or card-action traffic to reach command dispatch in affected deployments.
Impact
A deployment using Feishu webhook mode without a configured encryptKey, or handling malformed card-action callbacks with blank callback tokens, could fail open instead of rejecting the request. Severity remains critical because affected webhook deployments expose a network-triggered path into OpenClaw command handling without the expected Feishu signature or replay protection.

Fix
OpenClaw 2026.4.15 makes Feishu webhook and card-action validation fail closed. Webhook mode now refuses to start without an encryptKey, missing signing configuration returns invalid instead of valid, invalid signatures return 401, and blank card-action callback tokens are rejected before dispatch.
Verified in v2026.4.15:
extensions/feishu/src/monitor.transport.tsreturns invalid whenencryptKeyis missing, refuses webhook mode withoutencryptKey, and rejects invalid signatures before JSON handling.extensions/feishu/src/card-action.tsrejects blank callback tokens in the card-action lifecycle guard.extensions/feishu/src/monitor.webhook-security.test.tscovers missing-encryptKeystartup and transport rejection.extensions/feishu/src/monitor.card-action.lifecycle.test.tscovers malformed blank-token card actions being dropped before handler dispatch.

Связанные уязвимости
OpenClaw before 2026.4.15 contains an authentication bypass vulnerability in Feishu webhook and card-action validation that allows unauthenticated requests to reach command dispatch. Missing encryptKey configuration and blank callback tokens fail open instead of rejecting requests, enabling attackers to bypass signature verification and replay protection to execute arbitrary commands.
