Security checks for vulnerabilities and agentic risk

Overview

The skill is transparent about controlling Kia vehicles, but it asks users to run an unpinned remote package with account credentials and exposes a long-lived MFA-bypass token.

Review carefully before installing. Prefer a pinned and verified package version, avoid project-level `.mcp.json` for real credentials, use the narrowest `KIA_WRITE_MODE` possible, and do not export the refresh token unless you intentionally need to migrate a session and understand that it can bypass MFA.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Finding

Skill accesses MCP server configuration files (mcp.json). MCP configs contain server URLs, authentication tokens, and tool definitions — reading them allows the skill to discover and potentially abuse other tool integrations.
