If you’ve installed ClawHub plugins under the @openclaw or @clawhub scope and assumed they were vetted by the OpenClaw team — you may want to sit down. Researchers at Manifold Security have uncovered a significant supply-chain weakness in ClawHub’s plugin registry: 23 code-executing plugins were found squatting under official organizational scopes while being owned by entirely unrelated accounts.

The implications are serious. Any user who installed those packages had good reason to believe they were getting first-party, Anthropic-backed integrations. Instead, they may have been silently running arbitrary code from unknown third parties inside their AI agent environments.

What Is Scope Squatting?

In npm-style package registries, organizational scopes like @openclaw/ or @clawhub/ serve as namespacing signals. They imply that a package was published by, or at least verified by, the named organization. Developers — and by extension, AI agents doing automated skill installation — rely on this signal as a proxy for trust.

Scope squatting is a registry-level vulnerability where this trust signal breaks down. An attacker (or careless developer) publishes a package under a reserved or official-looking scope without actually controlling that organization’s registry account. If the registry doesn’t enforce scope ownership strictly, the counterfeit package inherits the credibility of the real scope.

This isn’t a new attack vector — it’s been documented in npm and PyPI ecosystems for years. But its appearance in an AI agent skill registry is a meaningful escalation, because the blast radius of a malicious plugin in an agentic context is much larger than a conventional developer dependency.

What Manifold Security Found

Ax Sharma, Head of Research at Manifold Security, published a detailed breakdown of the vulnerability in a research blog post. The key findings:

  • 23 packages in ClawHub’s catalog (out of approximately 1,508 total entries) were squatting under the @openclaw or @clawhub organizational scopes.
  • These packages were code-executing, meaning they weren’t just passive metadata — they ran arbitrary code when installed or invoked by an agent.
  • The packages appeared legitimate to users performing visual checks on scope names or browsing the registry UI.
  • Affected users would have had no easy way to distinguish these packages from genuine first-party integrations.

The research was independently corroborated by Help Net Security and GBHackers, establishing three separate sources confirming the same findings.

ClawHub’s Response

ClawHub has since updated its scope enforcement mechanisms, according to the verification notes in the Analyst’s report. The 23 affected plugins have been identified across the catalog.

This is encouraging, but the update doesn’t retroactively protect users who already installed affected packages before the policy change. If your agent runtime loaded one of these plugins, the arbitrary code execution already happened — or is still happening if the plugin persists in your agent’s skill set.

Why This Hits Agentic AI Harder

In a traditional software supply-chain attack, a malicious npm package might exfiltrate credentials or install malware on a developer’s machine. That’s bad. In an agentic AI context, the stakes are different:

  1. Agents operate with elevated autonomy. A plugin running inside OpenClaw or Claude Code can take real-world actions: send emails, modify files, call APIs, spawn sub-agents, and more. Malicious plugin code has access to everything the agent has access to.

  2. Automated installation is common. Many agentic workflows support skill auto-installation without requiring explicit human approval for every package. The “install from registry” step happens in the background.

  3. Scope names confer implicit trust in prompts. When an agent is instructed to “use the official @openclaw/analytics plugin,” it may install a squatted package without any red flags visible in the workflow logs.

  4. The verification gap is structural. Unlike traditional code review, there’s no mature tooling for auditing what an AI agent plugin actually does before it runs in production.

How to Protect Yourself

If you use ClawHub plugins in your agent setup, here are concrete steps you should take right now:

1. Audit your installed packages. List all currently installed ClawHub plugins and cross-reference them against the list of 23 confirmed squatted packages (see Manifold Security’s blog for the full registry of affected scopes and package names).

2. Verify scope ownership. For any package under @openclaw/ or @clawhub/, confirm that its publisher account actually belongs to the OpenClaw organization — not just that the scope name matches.

3. Check your runtime logs. If any of the affected packages ran inside your agent, review what actions were taken during that window. Look for unexpected API calls, file modifications, or external network requests.

4. Pin to verified versions. Once you’ve confirmed a plugin is legitimate, pin to a specific verified version rather than always pulling the latest. Version pinning limits your exposure to future substitution attacks.

5. Treat scope as a hint, not a guarantee. This incident is a good reminder that scope names — like domain names — can be imitated. Layer additional verification (checksum validation, audit logs, human review of new installs) into your agent deployment pipeline.

The Broader Supply-Chain Problem for AI Registries

ClawHub isn’t the first plugin marketplace to face scope-squatting, and it won’t be the last. What’s notable here is the scale: 23 affected packages in a catalog of about 1,500 represents a non-trivial 1.5% infection rate.

As AI agent frameworks mature and their plugin ecosystems grow, supply-chain security will become a first-class concern — not an afterthought. The same rigor applied to container image signing, npm audit, and Sigstore-style software attestation needs to be applied to agent skill registries.

Manifold Security’s research is a useful wake-up call. The fix isn’t just for ClawHub to patch their scope enforcement (which they have done). It’s for the entire community of agentic AI developers to treat plugin registries with the same skepticism we’ve learned to apply to any third-party dependency ecosystem.
