Security audit

IP2Location.io

Security checks for vulnerabilities and agentic risk

Overview

The lookup features fit the stated purpose, but setup can execute downloaded software without a clear approval step or defined limits.

Review the setup before enabling this skill. Install a reviewed CLI version yourself, or require explicit approval before the agent installs it. Check which additional agent skills the CLI installs or synchronizes. Lookup targets pass through OOMOL to IP2Location.io, so submit sensitive targets only when that disclosure is intended. No malicious intent was established; the Review verdict concerns installation control and unresolved installer effects.

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 (6)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied code performs remote software installation rather than searching or reading IP2Location.io data. Nothing in the chunk establishes that this installer is a supporting dependency for the declared purpose. The downloaded script's contents and resulting system changes cannot be determined from the supplied code.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
90% confidence
Finding

The supplied code's sole operation is a CLI login, rather than the declared IP2Location.io data access. Authentication could be a supporting implementation detail if the CLI were shown to serve IP2Location.io, but the supplied content establishes no such relationship.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable HTTPS download directly into bash executes remote code with the agent process's local privileges, without a pinned version or independent integrity verification. Compromise of the installer host or distribution pipeline could therefore cause arbitrary local code execution; the missing-CLI condition limits when this occurs but does not make execution safe.

The lookup workflow omits a privacy warning about sending queried IP addresses and domains to external services.

Medium
Category
Output Handling
Confidence
91% confidence
Finding

The workflow instructs the agent to submit lookup payloads through OOMOL to IP2Location.io and labels read actions as safe to run directly. Although the providers are named, there is no warning that queried IP addresses or domains—which may contain sensitive investigative or infrastructure information—are disclosed externally.

Content

No source excerpt is available for this finding.

The setup workflow executes downloaded installer scripts without warning about local system effects.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

A missing CLI triggers instructions to execute a remote installer without a separate approval step or explanation of local system changes. This expands a read-only lookup into local code execution, potentially modifying files and shell configuration or exposing user-accessible data; it overlaps with the SC2 finding rather than representing an independent exploit.

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.
