Email Outreach

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent email outreach helper with a local deliverability checker and no evidence of hidden access, persistence, exfiltration, or destructive behavior.

Install only if you want an assistant to help draft cold outreach and run local deliverability checks. Review generated outreach for legal, consent, and anti-spam compliance before sending, especially for bulk or lead-list use.

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

MCP Least Privilege
Confidence
88% confidence
Finding
The skill instructs the agent to read local repository files such as `references/copywriting-frameworks.md`, `assets/sequence-template.md`, and to run `scripts/deliverability_check.py`, but it declares no `permissions` or `allowed-tools` scope. That mismatch can lead to implicit or overly broad file/tool access at runtime, increasing the chance of unauthorized file reads or execution in environments that auto-grant capabilities.

Vague Triggers

Medium
Confidence
94% confidence
Finding
The trigger description covers many generic phrases like 'email templates', 'personalize emails', and 'lead outreach', which can cause the skill to activate in contexts broader than intended. Unintended invocation is risky here because the skill also encourages file access and script usage, potentially exposing extra capabilities when a simpler response would have sufficed.
