Short Menu

Security checks for vulnerabilities and agentic risk

Overview

Short Menu changes require approval, but missing-software setup directs the agent to execute a remote installer without asking first.

Review and install the oo CLI separately before enabling this skill, including its effects on other installed agent skills. Connect only the intended Short Menu account and retain confirmation for changes and deletions. OOMOL processes connector requests and manages service credentials. The bundled instructions were fully inspected, but external installers and live connector implementations were not verified; no malicious behavior was established.

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
98% confidence
Finding

The supplied command installs remote software; it does not show any Short Menu data operations. Nothing in the supplied content establishes this installer as a supporting dependency for Short Menu, so its behavior is materially different from the declared purpose. The installer contents are not provided, so its further effects cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a remotely fetched script directly into Bash executes whatever the endpoint returns with the agent process's local privileges, without a pinned version or independent integrity verification. A compromised distribution endpoint could therefore lead to local data theft or modification; the PowerShell alternative has the same risk. The documented vendor relationship and missing-CLI prerequisite reduce suspicion of malicious intent but do not eliminate the supply-chain exposure.

Fallback setup executes downloaded installation scripts without warning about local system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback instructs the agent to install software after a missing-command error without first explaining local system changes or obtaining approval. Authorization to manage Short Menu data does not necessarily authorize executing an installer on the local machine, although the conditional fallback limits when this risk arises.

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.
