Security audit

Function Acceptance Executor

Security checks for vulnerabilities and agentic risk

Overview

This Markdown-only skill is a coherent acceptance-testing guide, but users should run it only with test access and sanitized data.

Use this skill with staging or sandbox systems, least-privilege test accounts, and sanitized test data. Do not paste passwords, API keys, production secrets, or real customer data into the agent chat.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Finding

The trigger description and keywords are broad enough to match generic QA, verification, and regression-testing requests, which can cause this skill to activate outside a tightly scoped acceptance-testing context. That increases the chance the agent will solicit or process sensitive environment details, credentials, or test actions when a more limited or safer skill would have been appropriate.

Missing User Warnings

Finding

The skill asks for system access methods, accounts, environment information, and optional test data, but does not warn users about handling sensitive credentials, production systems, or real-user data. In practice, this can normalize unsafe sharing of secrets and encourage testing against live environments with real data, creating confidentiality, integrity, and privacy risks.
