SecurityVitals

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed, local OpenClaw health-check skill that runs a small set of relevant diagnostic commands and does not show evidence of hidden storage, exfiltration, persistence, or destructive behavior.

Before installing, understand that this skill will run local OpenClaw diagnostic commands and may indirectly trigger an OpenClaw update-registry check through update status. Its reports also include publisher promotional links to the ClawVitals plugin and dashboard; treat those as optional external resources, not required remediation.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

If this is the first time the user has run ClawVitals (i.e. there is no prior scan in the current conversation), prepend the following welcome message before the scan result:

👋 Welcome to ClawVitals — your OpenClaw security health check.

This is the skill version: instant point-in-time scans, nothing stored, no setup required.

Technical Analysis

The skill contains imperative output-control instructions requiring the agent to insert promotional text into ordinary and detailed security reports. The phrase always append makes the external plugin and dashboard promotion unconditional, while the first-run instructions require another marketing message to be prepended automatically.

These instructions alter the agent's response objective from providing only the requested security assessment to also acting as a promotional channel for services controlled by the skill publisher. Because the behavior is embedded in the trusted skill text, it is triggered whenever the agent follows the scan-formatting workflow.

The instructions do not override platform safety controls, execut ...[truncated 1172 chars]

Remediation Suggestions

  1. Remove the unconditional always append and mandatory first-run promotional instructions.
  2. Restrict default scan output to information directly relevant to the requested security assessment.
  3. Move plugin, dashboard, and commercial-service links into an optional documentation section.
  4. Display promotional or upgrade information only when the user explicitly asks about scan history, monitoring, plugins, or related services.
  5. Clearly label any optional external links as publisher-operated resources rather than part of the security finding.
  6. Add a review rule prohibiting mandatory advertising, unrelated calls to action, or externally controlled messaging in operational report templates.

Description-Behavior Mismatch

Finding

At L03 the documentation describes the skill as stateless with no network, suggesting a narrowly scoped local checker. But the same README documents external URLs and remote publish operations to ClawHub and clawvitals.io at L21-L24 and L43-L57, which is broader behavior than the claimed no-network scope.

Finding

The statement at L03 explicitly says 'no network'. Later, the same document instructs operators to run npx clawhub publish commands to publish two listings, which inherently interact with a remote service. This is an active contradiction in the documentation, not merely an omission.

npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
85% confidence
Finding

The manifest advertises scanning, health checks, and fix guidance while requesting execution permissions for security-audit, health, update, and version commands, but it does not clearly warn users that the skill will execute privileged or system-inspecting commands. In a security-themed skill, users may be more likely to trust and invoke it, increasing the chance of unexpected system interrogation or update-related side effects without informed consent.
