Navigatr

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Navigatr connector that can read and change badge data through OOMOL, with explicit confirmation rules for write and destructive actions.

Before installing, be comfortable using OOMOL as the broker for your Navigatr account and review the live schema before approving any write or destructive action. For first-time setup, prefer OOMOL's official installation documentation or verify installer sources before running pipe-to-shell commands.

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

External Script Fetching

Finding

The skill instructs users to install software via a remote script piped directly into a shell, which creates a supply-chain and remote code execution risk if the hosting endpoint, transport, or script contents are compromised. In this skill context, the danger is increased because the installation command is presented as a fallback operational step, making it likely to be copied and run without independent verification.

Finding

The description says to use this skill for "ANY Navigatr request" and "Whenever a task involves Navigatr," which is a very broad trigger for a markdown skill description. It does not provide tighter scope boundaries or negative examples, so ordinary references to Navigatr could invoke the skill unnecessarily.
