How to Fix CVE-2026-32974

To remediate this vulnerability, upgrade all affected OpenClaw dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

openclaw fixed: 2026.3.12
npm install openclaw@2026.3.12
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls openclaw

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-32974, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of OpenClaw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.3.12), your application is affected.

Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-347: Improper Verification of Cryptographic Signature, where the product does not verify, or incorrectly verifies, the cryptographic signature for data. In OpenClaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
