Apple Mail Search Safe.Bak

Security checks for vulnerabilities and agentic risk

Overview

The skill is a disclosed Apple Mail search helper that can read email contents and uses an external npm CLI, so it should be installed and used with care but does not show deception or destructive behavior.

Install only if you are comfortable giving the CLI and your agent access to Apple Mail search results and full message bodies. Prefer narrow queries, avoid requesting body text unless needed, and consider verifying or pinning the npm package before installation.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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

Finding

The skill explicitly supports reading full email body text from Apple Mail, but the documentation does not clearly warn users that invoking these commands can expose sensitive mailbox contents such as personal, financial, or authentication-related information to the agent or downstream tools. In an agent setting, this omission increases the chance of over-collection and unintended disclosure because users may treat a search utility as low-risk metadata lookup rather than full-content access.
