  "details": "## Summary\n\nFeishu 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.\n\n## Impact\n\nA 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.\n\n## Affected versions\n\n- Affected: `\u003c 2026.4.15`\n- Patched: `2026.4.15`\n\n## Fix\n\nOpenClaw `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.\n\nVerified in `v2026.4.15`:\n\n- `extensions/feishu/src/monitor.transport.ts` returns invalid when `encryptKey` is missing, refuses webhook mode without `encryptKey`, and rejects invalid signatures before JSON handling.\n- `extensions/feishu/src/card-action.ts` rejects blank callback tokens in the card-action lifecycle guard.\n- `extensions/feishu/src/monitor.webhook-security.test.ts` covers missing-`encryptKey` startup and transport rejection.\n- `extensions/feishu/src/monitor.card-action.lifecycle.test.ts` covers malformed blank-token card actions being dropped before handler dispatch.\n\nFix commit included in `v2026.4.15` and absent from `v2026.4.14`:\n\n- `c8003f1b33ed2924be5f62131bd28742c5a41aae` via PR #66707\n\nThanks to @dhyabi2 for reporting this issue.",
