Security checks for vulnerabilities and agentic risk

Overview

The skill uses AppGoat for clearly described app-market research, with optional monthly reports and GitHub issue creation.

AppGoat receives your search terms and consumes credits. Generalize confidential ideas. If enabling automation, pin the playbook revision, check repository visibility before posting reports, and disable the schedule when finished.

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
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
Findings (5)

The workflow sends user-derived app ideas to AppGoat without a privacy warning.

Finding

The workflow derives seed terms from the user's niche or proposed app idea and submits them to AppGoat's keyword_research service. Although the skill names AppGoat and describes its public read tools, it does not warn that user-provided idea details will be transmitted to a third party, which matters for confidential or unreleased concepts.

Without the AppGoat MCP server, call the API directly. Base URL `https://api.appgoat.ai/v1`,
header `x-api-key: $APPGOAT_API_KEY` (create a key at https://dash.appgoat.ai). Responses are
`{ "data": …, "meta": { "credits_used", "credits_remaining", … } }`; errors carry `error.hint`.
