CVE-2026-32974
OpenClaw: Feishu webhook mode accepted forged events when only `verificationToken` was configured
Description
### Summary Feishu webhook mode allowed deployments that configured only `verificationToken` without `encryptKey`. In that state, forged inbound events could be accepted because the weaker configuration did not provide the required cryptographic verification boundary. ### Impact An unauthenticated network attacker who could reach the webhook endpoint could inject forged Feishu events, impersonate senders, and potentially trigger downstream tool execution subject to the local agent policy. ### Affected versions `openclaw` `<= 2026.3.11` ### Patch Fixed in `openclaw` `2026.3.12`. Feishu webhook mode now fails closed unless `encryptKey` is configured, and the webhook transport rejects missing or invalid signatures before dispatch. Update to `2026.3.12` or later and configure `encryptKey` for webhook deployments.
