Smart Update Agent

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed enterprise update-management skill with broad but purpose-aligned read, write, and command-execution needs.

Install this only if you want an agent to help manage skill/runtime updates with command execution and file changes. Review the cron schedule, auto-promote settings, backup paths, audit log retention, and webhook destinations before enabling automation, and require confirmation for production or bulk updates.

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

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The skill describes backup, rollback, file-writing, and command-execution behavior but does not prominently warn users that these actions may modify the local system or managed environments. In an update-management context, that omission is significant because users may treat the skill as advisory while it is positioned to perform state-changing operations through write and exec.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The trigger phrase is broad enough to match ordinary requests about setting up automatic updates, which increases the chance the skill activates in contexts where the user did not intend enterprise-grade update orchestration or command execution. Because the skill advertises read/write/exec capabilities and system-modifying behavior, overbroad activation can lead to unintended changes or risky guidance being applied too eagerly.

Intent-Code Divergence

Medium
Category

Confidence
90% confidence
Finding

The error-handling guidance tells the agent to run a network connectivity test ('ping', firewall, proxy checks) when required input is missing, which is unrelated to the declared purpose of update orchestration guidance. In a skill that has exec capability, this can cause unnecessary command execution and environment probing without clear user intent, expanding the action scope beyond the requested task.

Missing User Warnings

Confidence

Finding

The skill supports callback or alert URLs but does not warn that update metadata, environment details, or audit information may be sent to third-party endpoints. This can cause inadvertent disclosure of operational data, especially in enterprise settings where update histories and environment names may be sensitive.

Natural-Language Policy Violations

Confidence

Finding

The phrase '完全中文化表达,适配中文用户企业级场景' indicates a Chinese-language localization target, but the document does not offer users a language choice or state that the locale restriction is optional. This can be a language policy concern when a skill effectively assumes a specific language without opt-in.
