posture-patrol

Security checks for vulnerabilities and agentic risk

Overview

This is a local posture-tracking CLI whose behavior matches its stated purpose, with some wellness/medical-disclaimer and local-data-storage caveats.

Reasonable to install if you want a local posture log and are comfortable with profile details and notes being saved in ~/.posture_patrol.json. Treat stretch and symptom guidance as general wellness information; seek qualified medical care for pain, numbness, tingling, weakness, worsening symptoms, or persistent issues.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
94% confidence
Finding

The skill documentation describes a Python CLI that reads and writes a local JSON database (~/.posture_patrol.json), but the manifest does not declare any explicit tool scope or permissions. This creates a trust and policy gap: a host or reviewer cannot easily tell that filesystem access is required, and an over-permissive runtime could allow unintended file access beyond the expected posture data file.

Missing User Warnings

Confidence

Finding

This file provides medical-adjacent guidance, describes symptoms such as tingling and nerve compression, predicts long-term harms, and recommends corrective exercises without a clear user-facing disclaimer that it is educational rather than professional medical advice. In a posture-tracking skill, users may rely on these statements for self-diagnosis or self-treatment, which can delay appropriate care or worsen underlying conditions if red-flag symptoms are present.

Missing User Warnings

Confidence
89% confidence
Finding

This code stores user-entered profile details and freeform notes in a JSON database under the user's home directory, and later writes that data with save_db(). Although the file path is visible in code, there is no print statement, confirmation, or docstring warning telling users that their inputs will be persisted locally.
