Security audit

People Data Labs

Security checks for vulnerabilities and agentic risk

Overview

The data-search workflow is coherent, but its setup can execute changing remote code and introduce broader changes to your agents’ installed skills.

Review the setup before enabling this skill. Prefer a verified, preinstalled CLI and explicitly control its automatic skill synchronization. Only submit identifiers and queries you intend to share through OOMOL with People Data Labs, and check usage charges. The remote installers could not be inspected, and current publisher documentation cannot establish the behavior of every downloaded version.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command performs remote script execution and apparently installs an Oomol CLI; it does not search or read People Data Labs data. No evidence establishes this installer as a supporting dependency for the declared purpose. The downloaded script's additional behavior cannot be determined from the supplied code.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The setup instructions pipe a remotely fetched, unpinned script directly into Bash without integrity verification or an explicit approval step; the PowerShell alternative has the same execution pattern. If the distribution endpoint or its supply chain is compromised, a missing-CLI error can lead to arbitrary code execution with the agent process's permissions, despite the skill's otherwise read-oriented purpose.

The execution workflow lacks a privacy warning for person-enrichment and search payloads sent to external services.

Medium
Category
Output Handling
Confidence
88% confidence
Finding

The workflow instructs the agent to submit action payloads and labels all untagged reads as safe to run directly. Person-enrichment and search requests can include personal identifiers or sensitive search criteria transmitted through OOMOL to People Data Labs, but the skill does not warn users about that disclosure; read-only operations can still affect privacy.

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.
