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-2026-34508, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of Duplicate Advisory 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-307: Improper Restriction of Excessive Authentication Attempts, where the product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame. In Duplicate Advisory, 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

### Duplicate Advisory This advisory has been withdrawn because CVE-2026-34508 has been rejected as a duplicate of CVE-2026-34505. This link is maintained to preserve external references. ### Original Description OpenClaw before 2026.3.12 applies rate limiting only after webhook authentication succeeds, allowing attackers to bypass rate limits and brute-force webhook secrets without triggering 429 responses. Attackers can repeatedly guess invalid secrets to discover valid credentials and subsequently submit forged Zalo webhook traffic.
