Security audit

cold email sequence lite

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small offline cold-email drafting helper whose code matches its stated purpose and does not show hidden data access, persistence, or network behavior.

Reasonable to install if you want an offline helper for drafting two-touch cold outreach skeletons. Prefer installing from a reviewed or pinned source when possible, and review generated outreach so it is only used for legitimate prospects and not mass unsolicited spam.

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

Finding

The README instructs users to run npx skills without pinning a specific version, which can cause execution of whatever package version is current at install time. If the upstream package is compromised or a breaking/malicious version is published, users following the documentation could execute untrusted code on their systems.

Finding

The description says to use the skill when the user asks to "write cold outreach or a simple drip email," which is a broad natural-language trigger without clear boundaries or exclusion conditions. This can overlap with ordinary writing requests and does not specify what kinds of outreach requests should not activate the skill.
