WhatsApp skill 1

Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly disclosed WhatsApp CLI helper, but users should understand that history sync and search can expose private message content.

Install only if you want the agent to operate a WhatsApp CLI on your behalf. Be careful with sync, search, show, and backfill requests because they may reveal private chats and metadata; prefer narrow chat IDs, date ranges, and limits, and confirm recipients and message text before sending.

A.I.G

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

Finding

The skill explicitly enables syncing, searching, showing, and backfilling WhatsApp history, which can expose large amounts of private message content and metadata. While the file includes some operational safety around sending messages, it does not warn that these commands access privacy-sensitive communications or require heightened user consent before retrieval and inspection.
