Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed deep-research workflow that uses web search and report generation, with some usability and packaging caveats but no artifact-backed malicious behavior.

Install this if you want a long-form research-report workflow and are comfortable with it performing web searches and creating a PDF. Before relying on PDF generation, verify that the missing md_to_pdf.py script comes from a trusted source, and avoid giving sensitive private research topics unless external search is acceptable.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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
95% confidence
Finding

The activation description is broad enough to trigger on many generic research-related requests, which can cause the skill to engage unexpectedly and steer conversations into long-form web research and report generation. While not overtly malicious, this increases the chance of unanticipated tool use and scope expansion without clear user intent.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The skill promises a PDF as the final output but does not disclose that a file will be created as a side effect. Hidden file creation can surprise users, create storage/privacy issues, and normalize executing output-producing workflows without explicit consent.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill mandates online searching and parallel sub-agent collection without notifying the user that external network requests will occur. This can expose user-supplied topics or sensitive interests to third-party services and causes undisclosed data egress beyond the local conversation context.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The instruction to use a local conversion script introduces code execution and file-generation behavior without explaining what the script does, what dependencies it invokes, or what files it reads and writes. Even if intended for formatting, undisclosed script execution increases the attack surface and can lead to unsafe local side effects if the environment or script is modified.
