OpenClaw before 2026.3.12 contains an authentication bypass vulnerability in Feishu webhook mode when only verificationToken is configured without encryptKey, allowing acceptance of forged events. Unauthenticated network attackers can inject forged Feishu events and trigger downstream tool execution by reaching the webhook endpoint.

Detection & IOCsextracted from sources · hover to see the quote
- →Target the Feishu webhook endpoint of OpenClaw; unauthenticated POST requests to this endpoint with forged Feishu event payloads (no encryptKey validation) are indicative of exploitation attempts. ↗
- →Alert on OpenClaw (formerly Moltbot or Clawdbot) instances running versions prior to 2026.3.12 that have verificationToken configured but no encryptKey set, as these are vulnerable to forged event injection. ↗
- ·The vulnerability is only present when OpenClaw is configured in Feishu webhook mode with verificationToken set but encryptKey NOT configured. Deployments using encryptKey are not affected by this bypass. ↗
- ·No public exploit is known at this time, reducing immediate exploitation risk, though EPSS probability is non-trivial at 18.1 percentile. ↗

OpenClaw: Feishu webhook mode accepted forged events when only `verificationToken` was configured
ghsa·2026-03-13
CVE-2026-32974 [HIGH] CWE-347 OpenClaw: Feishu webhook mode accepted forged events when only `verificationToken` was configured
OpenClaw: Feishu webhook mode accepted forged events when only `verificationToken` was configured
### 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 mis
