Security Vulnerability Scanner

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple local code-pattern vulnerability scanner with no evidence of hidden execution, persistence, credential access, or data exfiltration.

This skill appears safe to install for local, pattern-based code review, but users should know it is lightweight and may produce false positives or miss real vulnerabilities. The publisher should narrow the generic "vulnerability" trigger and document language behavior more clearly.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The natural-language description and feature list force a specific language for user-facing behavior, but the file does not offer user opt-in or explain that the skill is intentionally region- or locale-specific. This can violate language or locale policy requirements for user choice.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger phrase "vulnerability" is extremely broad and can match many unrelated user requests, causing this skill to activate outside its intended scope. Over-broad activation can lead to accidental invocation, context hijacking, or interference with other more appropriate skills, especially in multi-skill agent environments.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The trigger pattern list includes the generic English term "vulnerability", which is broad enough to match many unrelated user requests and cause the skill to activate unexpectedly. Because this skill performs security analysis, unintended invocation could lead to incorrect routing, confusing results, or exposure of user-supplied code to a skill they did not explicitly intend to use.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
73% confidence
Finding

The natural-language trigger section includes both Chinese and English phrases, but the file does not explain language selection behavior or whether invocation is limited to particular locales. This can create an implicit language policy without an explicit user-facing choice or documented justification.
