Security audit

Cert Manager

Security checks for vulnerabilities and agentic risk

Overview

This skill is a low-risk static reference helper that prints local text and does not access credentials, networks, or persistent system settings.

This appears safe to install from a security perspective, but users should treat it as a very shallow generic reference rather than authoritative cert-manager documentation.

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

Credential Access

Privilege Escalation
Confidence
70% confidence
Finding

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

Description-Behavior Mismatch

Finding

The manifest describes a quick lookup/reference tool for Cert Manager concepts, best practices, and implementation patterns. However, every command prints broad placeholder-style text about generic 'cert manager' security workflows, installation, migration, and performance, with no concrete Cert Manager concepts, APIs, resources, issuers, certificates, ACME flows, or implementation details a real reference tool would be expected to provide.

Intent-Code Divergence

Confidence

Finding

The top-of-file comment says this is a 'cert-manager — Cert Manager reference tool' to use when working with cert manager in security contexts. In practice, the script does not provide Cert Manager-specific reference behavior; it dispatches only to static, mostly domain-generic help text, which contradicts the documented intent of being a Cert Manager reference tool.
