LightSpeed VT

Security checks for vulnerabilities and agentic risk

Overview

The LightSpeed VT functions are appropriately scoped, but setup can run unverified remote installers without clear approval or limits on local changes.

Review the setup path before enabling this skill. Prefer an independently installed, integrity-verified CLI, and check whether it installs or updates other agent skills. Connect only the intended LightSpeed VT account and consider OOMOL's role in handling requests and credentials. The complete bundled artifact was inspected, but remote installer and connector behavior 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
Vulnerability Patterns

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The declared purpose concerns accessing LightSpeed VT data, but the supplied command executes an Oomol-hosted installer. No connection to LightSpeed VT functionality is established, so this cannot be treated as a demonstrated supporting implementation detail. The downloaded script's contents and further effects are not available for assessment.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The command pipes a mutable HTTPS response directly into Bash without pinning a release or verifying its integrity. HTTPS protects transport but not against compromise of the distribution source, so the installer could execute arbitrary commands and access files or credentials available to the process; its conditional setup role reduces exposure but does not remove the risk.

Fallback setup executes remotely downloaded installation scripts without warning about system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
97% confidence
Finding

The fallback directs an agent to execute downloaded shell or PowerShell code without requiring user approval, integrity verification, or an explanation of host changes. A missing CLI during an otherwise read-only task can therefore trigger host-level installation; a compromised installation source could execute arbitrary code with the invoking user's privileges.

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.
