Security checks for vulnerabilities and agentic risk

Overview

The lookups fit the stated purpose, but setup executes unverified remote code and the linked CLI documents broader changes to installed agent skills.

Review and install a verified CLI version yourself before agent use. Consider disabling its documented startup skill synchronization with OO_SKILLS_SYNC_DISABLED=1. Send only information authorized for each lookup and expect possible credit usage. The remote installers and hosted connector implementation were not inspected.

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 declared purpose concerns Gender-API.com data access, but the supplied command executes an installation script hosted on cli.oomol.com. Nothing in the supplied chunk establishes that this installer supports the declared service. Remote installer execution is a materially different, undeclared capability; the script's downstream behavior cannot be determined from this chunk.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
90% confidence
Finding

The supplied code only invokes a login command. It contains no Gender-API.com reference, search operation, or data-reading operation. Although authentication can support API access, nothing in this chunk connects the oo login to the declared service, so its observed purpose does not match the description.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The setup command downloads a mutable remote script and immediately executes it without a pinned version or independent integrity verification; the PowerShell alternative has the same weakness. Compromise of the installer delivery infrastructure could execute arbitrary commands with the invoking user's privileges, although the missing-CLI prerequisite limits when this path is reached.

Read actions are labeled safe to run directly without warning that lookup inputs are sent to a third-party service.

Output Handling
Confidence
92% confidence
Finding

Calling every untagged read safe to run directly conflates absence of state changes with absence of privacy risk. These lookups can transmit names, email addresses, and IP hints through OOMOL to Gender-API.com; an explicit user-requested lookup reduces concern, but the blanket rule does not guard against sending unrelated or sensitive contextual data.

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.
