Security checks for vulnerabilities and agentic risk

Overview

This skill is a broad frontend automation guide with command access and unsupported security claims, so users should review its scope before installing.

Install only if you are comfortable with a broad, template-like skill that may use read and exec for frontend work. Treat its security claims as unverified, keep API keys in environment variables rather than prompts, review commands before execution, and avoid using it on sensitive repositories or credentials without additional safeguards.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The activation/usage description is extremely broad, covering generic efficiency, automation, batch processing, and workflow optimization. In agent ecosystems, such overbroad wording can cause the skill to be invoked for unrelated or higher-risk tasks than intended, especially since the skill also lists powerful capabilities like exec.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill claims built-in data encryption and access control, but the provided content contains only marketing/documentation text and no concrete implementation, configuration, or enforcement details. In an agent skill that may handle user data, this can mislead operators into trusting protections that do not actually exist, increasing the risk of unsafe data handling or disclosure.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The document advertises '内置安全检查' and stronger security/compliance properties without any corresponding logic, policy, or validation steps in the skill content. This creates a false sense of safety around automated processing and may cause users to submit sensitive data or allow risky operations under the assumption that safeguards are present.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

This section instructs users to configure API keys, establish API connections, execute commands, and handle files/outputs, but it lacks clear warnings about secret exposure, destructive command risk, file overwrite, privilege misuse, or external data exfiltration. Given that the skill declares tools including exec and read, the absence of strong safety boundaries makes misuse more dangerous in context.
