Apple Mail Search

Security checks for vulnerabilities and agentic risk

Overview

This skill is a read-only Apple Mail metadata search helper, but users should understand it can reveal and export private email details.

Install only if you are comfortable letting the agent query local Apple Mail metadata. Use narrow searches and small limits, avoid broad CSV/JSON exports unless needed, and remember exported files may persist private email subjects, addresses, dates, and attachment names.

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

Vague Triggers

Medium
Category

Confidence
95% confidence
Finding

The description uses very broad activation phrases like 'find, search, or list emails,' which can cause the skill to trigger on many ordinary user requests without making clear that it will query a sensitive local mail database. Because this skill accesses private email metadata, overly generic routing language increases the risk of unintended invocation and privacy-impacting data access.

Missing User Warnings

Medium

Confidence
97% confidence
Finding

The skill documentation does not prominently warn that it queries the user's local Apple Mail SQLite database and can output or export sensitive email metadata such as subjects, senders, recipients, dates, and attachment names. Without a clear privacy warning and consent boundary, users may invoke the skill without understanding that private communications data can be searched, serialized to JSON/CSV, or redirected to files.
