Security audit

Cgroup

Security checks for vulnerabilities and agentic risk

Overview

This skill only prints generic sysops template text while claiming to be a cgroup reference, which could mislead users doing system administration work.

Review before installing or relying on it. It does not appear to perform unsafe local actions, but it should not be trusted as an accurate cgroup reference until its content is replaced with real, reviewed cgroup-specific material.

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

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.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The script is presented as a cgroup reference tool, but nearly all output is generic placeholder documentation unrelated to Linux cgroups. This kind of functionality/documentation mismatch can mislead operators into trusting inaccurate guidance during system administration tasks, increasing the chance of unsafe operational decisions.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The help text and command set claim to provide cgroup guidance, but the implementation serves contradictory generic templated content. In a sysops context, deceptive or incorrect labeling is dangerous because users may rely on the tool for privileged operational work and receive irrelevant guidance instead of accurate cgroup procedures.
