GKE Autopilot Hardening

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed external API helper for generating GKE Autopilot hardening configuration, with no local code execution or persistence, but users should avoid sending sensitive identifiers.

Before installing, confirm you are comfortable sending selected hardening options and request metadata to the listed third-party API. Use pseudonymous session IDs, omit userId/timestamp unless needed, and review generated Kubernetes manifests before applying them to a cluster.

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
93% confidence
Finding

The skill documents request fields such as sessionId, userId, and timestamp while presenting an external API workflow, but it does not warn users that these potentially identifying values will be transmitted to a third-party service. This creates a privacy and data-governance risk because users may unknowingly send internal identifiers or audit-correlated metadata outside their environment.

External Transmission

Medium
Category
Data Exfiltration
Confidence
88% confidence
Finding

The skill references an external service endpoint, meaning users of the skill may send cluster hardening selections and associated metadata to infrastructure outside their trust boundary. In the context of a security-hardening tool, this is more sensitive because configuration choices, tenant identifiers, and usage patterns can reveal aspects of an organization's security posture and internal operations.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
84% confidence
Finding

This is a manifest/config file, so vague-trigger rules apply. The description "Generate GKE AutoPilot hardening configurations" is generic and provides no limiting conditions, examples, or exclusions, which could lead to unintended invocation in systems that rely on manifest text for routing or activation.
