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.
