Security audit

Newsletter & Creator Pack

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed newsletter/content workflow skill with limited local file output and no executable payloads or hidden behavior.

Before installing, users should know it may research sponsor prospects online and may save generated drafts or reports locally under the configured Documents output path after confirmation. Avoid pasting sensitive subscriber data unless the environment and save location are appropriate.

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
Not specified by scanner
Confidence
91% confidence
Finding

The activation guidance is broad enough to trigger on generic writing and analysis requests that extend beyond a narrowly scoped newsletter tool. This can cause unintended invocation, increasing the chance the skill handles unrelated user content, performs unnecessary data processing, or applies file-writing behavior in contexts where the user did not clearly intend to use this skill.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill instructs the agent to save generated content to a fixed local path, but the skill description does not clearly disclose local file creation and retention behavior. This can surprise users, persist potentially sensitive business content on disk, and create privacy or data hygiene issues if the environment is shared or monitored.
