Security audit

Mlfinlab

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local plain-text reference helper with minor documentation quality issues but no credential access, network behavior, persistence, or destructive actions.

This appears safe to install from a security standpoint, but expect generic reference output and a couple of small documentation inconsistencies rather than authoritative mlfinlab-specific guidance.

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
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Finding

The help output says mlfinlab v$VERSION, which implies it will show the actual version. Because the here-document delimiter is single-quoted (<< 'HELPEOF'), shell expansion is disabled and users will see the literal text $VERSION instead of 2.0.1, contradicting the apparent documentation intent.

Confidence

Finding

The cheatsheet presents troubleshooting as an available command, but the dispatcher only implements debugging, not troubleshooting. This is an active mismatch between embedded documentation and actual behavior, and users following the cheatsheet would get an unknown-command error.
