Docker Hardening

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed API-backed Docker hardening generator, with a privacy caveat because requests go to an external service with session metadata.

Use this only when you are comfortable sending Docker hardening choices and request metadata to the provider's API. Avoid including secrets, private hostnames, internal topology, or account identifiers in option values unless you trust the provider's retention and privacy practices.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill requests sessionId, userId, and timestamp and describes use for tracking and audit purposes, but it does not clearly warn that these identifiers and request metadata may be sent to an external third-party API endpoint. This creates a transparency and privacy risk because users may unknowingly disclose operational or potentially identifying metadata outside their environment.

External Transmission

Medium
Category
Data Exfiltration
Confidence
90% confidence
Finding

The skill explicitly references an external API endpoint, which means user-supplied hardening options and associated metadata will leave the local trust boundary. In this context, the danger is not inherently code execution but potential leakage of infrastructure details, identifiers, and usage metadata to a third party, especially since the skill markets itself as a security tool that may be used with sensitive deployment information.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

This is a manifest-style file, so vague-trigger review applies. The top-level description states a broad capability as a 'Professional Docker Security Configuration Generator' without clarifying when this skill should or should not be invoked, and it provides no exclusion conditions or narrowly scoped trigger phrases.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
89% confidence
Finding

For markdown and manifest-style descriptions, missing-warning findings apply when the skill omits warnings about privacy-relevant behavior. The schema collects sessionId, optional userId, and timestamp, but the API description provides no user-facing notice about handling identifiers or associated privacy considerations.
