Security checks for vulnerabilities and agentic risk

Overview

This skill is a real watchdog, but its setup can create persistent OpenClaw cron jobs that send raw diagnostic output to Telegram, including a hardcoded fallback recipient the user may not control.

Review carefully before installing. Only run setup if you understand that it will create persistent OpenClaw cron jobs and Telegram announcements. Configure your own Telegram recipient first, remove the hardcoded fallback, add an uninstall path, and avoid sending raw diagnostic output externally unless it is redacted.

Vulnerability Patterns
  • System PersistenceInstalls backdoors, hooks, services, or scheduled tasks that survive the run
  • Tool Hijacking and SpoofingModifies or replaces tools so legitimate-looking calls execute attacker logic
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

The recipient's ownership is not established, and the user is not asked to approve it. The installed cron message directs an Agent to include the watchdog's full raw output whenever the verdict is unhealthy or recovery actions occur.

Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The declared purpose frames the skill as a watchdog/validator, but the documented behavior extends to installation into workspace directories, recurring cron/job creation, orchestration changes, and Telegram notification with a fallback recipient. This mismatch is dangerous because users may invoke what appears to be a diagnostic skill while actually granting persistence, environment modification, and potential data egress.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
92% confidence
Finding

The skill advertises user-invocable shell-based operations but does not declare any tool scope or permission boundaries. That omission weakens reviewability and consent, because operators cannot easily tell that the skill will execute shell commands capable of modifying the local OpenClaw environment.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The script silently falls back to a hard-coded Telegram recipient when no configured destination exists, creating an unauthorized outbound communication path. In a security-sensitive automation context, embedding a default external recipient is highly suspicious because it can exfiltrate operational status or future agent-generated content to a third party without informed operator consent.

No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The setup script creates or modifies persistent cron jobs that periodically invoke an agent and deliver results over Telegram, which extends the skill from a bounded local watchdog into an ongoing autonomous messaging capability. That persistence and external delivery channel increase the blast radius of any prompt manipulation, misconfiguration, or future script changes, and the behavior is not tightly constrained to local-only recovery.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

This code creates and later removes a lock directory and writes a PID file, which are file-write operations, without any confirmation prompt, user-facing print, or explanatory comment/docstring describing the side effect. The script also proceeds to perform self-healing actions automatically, so the file-system modification is not clearly disclosed to the user at the point of action.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The function restarts the openclaw gateway via systemctl or CLI, which is a potentially disruptive system operation. Although failures and outcomes are recorded in internal details, there is no clear user-facing warning, confirmation, or explanatory comment that the script may restart a service as part of self-healing.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
87% confidence
Finding

This function actively contacts remote agents using openclaw agent and transmits a message payload, but the script provides no warning or explanatory comment that it will send probe messages to configured agents. Because this transmits data to external components, it should be disclosed somewhere in the code or user-facing output.
