Security audit

Positionstack

Security checks for vulnerabilities and agentic risk

Overview

The location lookups fit the skill’s purpose, but automatic setup executes unverified downloaded software and can introduce additional agent skills without clearly disclosing those changes.

Review and install a fixed CLI release yourself before enabling this skill. Check whether you want its additional agent skills; the publisher documents OO_SKILLS_SYNC_DISABLED=1 to disable startup synchronization in its [command reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md). Share only location information you intend OOMOL and Positionstack to receive. The bundled instructions were fully inspected, but remote installers and hosted 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

Findings (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command performs remote code execution for an apparent CLI installation, not a Positionstack operation. Nothing in the supplied chunk establishes that this installation is a supporting requirement for Positionstack access. The downloaded script is not supplied, so its additional behavior cannot be assessed.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied code performs a CLI login rather than a Positionstack search or data-read operation. Authentication could be a supporting implementation detail if tied to Positionstack, but the supplied chunk establishes no such connection.

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

The setup instructions pipe a mutable remote script directly into Bash without version pinning or independent integrity verification; the PowerShell alternative has the same weakness. If the distribution endpoint or its publishing pipeline is compromised, following these instructions could execute attacker-controlled code with the agent's local permissions, exposing files and credentials. The missing-CLI condition limits exposure but does not make execution safe.

Geocoding requests transmit potentially sensitive location data without a privacy warning.

Medium
Category
Output Handling
Confidence
92% confidence
Finding

The workflow instructs the agent to execute connector actions with payloads that can contain addresses, coordinates, or IP addresses. Although it identifies OOMOL and Positionstack, it does not warn that these potentially sensitive inputs are transmitted to external services; the safety section instead treats read actions as safe to run directly.

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.
