Security audit

Google Maps

Security checks for vulnerabilities and agentic risk

Overview

The Maps features fit their purpose, but setup can execute unverified remote code and introduce additional agent skills without clearly explaining those changes.

Review and install a specific CLI version separately before use. If you only want Maps support, disable automatic skill synchronization before invoking the CLI. Location queries pass through OOMOL to Google, and usage may incur charges. This review covered the complete packaged skill; the remote installers and deployed connector implementation remain unverified.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command performs remote script execution, not Google Maps searching or data retrieval. Nothing in the chunk establishes that installing the Oomol CLI is a supporting requirement for the declared purpose. The downloaded script's contents and subsequent effects are not provided.

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

The setup instructions pipe a remotely fetched, unpinned script directly into Bash without integrity verification or review; the PowerShell alternative has the same execution pattern. A compromised distribution endpoint or malicious installer update could execute arbitrary commands with the agent's local privileges, exposing files and credentials, although the missing-CLI prerequisite limits when this path is reached.

The workflow sends location-related user data through OOMOL to Google Maps without a privacy warning.

Medium
Category
Output Handling
Confidence
92% confidence
Finding

The workflow instructs the agent to submit action payloads, which can include user-provided addresses, coordinates, and route endpoints. Although the connector architecture is described, the skill does not warn that these potentially sensitive inputs are transmitted to OOMOL and Google; its blanket statement that read actions are safe to run directly overlooks this privacy impact.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
