Elecz

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed, read-only electricity-price helper that uses a remote MCP service and does not include code, persistence, credential access, or hidden agent-control behavior.

Install only if you are comfortable using Elecz's remote MCP service for electricity price lookups. The skill says it sends zone and optional consumption/heating inputs, and it should be treated as advisory before changing contracts or automating devices such as EV chargers or appliances.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category

Confidence
92% confidence
Finding

The phrase 'Any question involving electricity spot prices, contract comparison, or energy optimization' is a very broad activation condition. Although the skill includes some negative examples, 'energy optimization' is expansive and could overlap with common user requests outside the intended electricity-price scope.

Missing User Warnings

Confidence

Finding

The markdown instructs agents to use output fields 'for direct automation decisions' and scheduling longer tasks, but it does not include a caution that any resulting device control or scheduling actions may affect user systems or costs. For markdown files, behaviors that can affect user data or system integrity should be accompanied by an explicit warning.
