How to Fix CVE-2026-35664

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: 2026.3.28 
npm install openclaw@2026.3.28
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-2026-35664, 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 2026.3.28), 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.

Source Advisory Statement

## Summary Feishu Raw card Send Surface Can Mint Legacy Card Callbacks That Bypass DM Pairing ## Affected Packages / Versions - Package: `openclaw` - Affected versions: `<= 2026.3.24` - First patched version: `2026.3.25` - Latest published npm version at verification time: `2026.3.24` ## Details Feishu raw card sends could previously mint legacy callback payloads that bypassed DM pairing and let unpaired recipients reach callback handling. Commit `81c45976db532324b5a0918a70decc19520dc354` rejects legacy raw-card command payloads so callbacks stay on the normal paired path.
