Security audit

GageList

Security checks for vulnerabilities and agentic risk

Overview

GageList changes require approval, but the CLI dependency can silently install additional agent skills beyond the stated task.

Review and install a verified CLI release yourself. If you do not want additional agent skills installed or synchronized, configure OO_SKILLS_SYNC_DISABLED=1 before invoking the CLI. OOMOL processes connector requests, so connect only the intended GageList account and retain write/delete approvals. The remote installers remain unverified, and the skill does not pin the dependency 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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied code performs remote script execution rather than GageList data operations. Nothing supplied establishes that this installer is a supporting dependency for GageList. The remote script's contents and any resulting system changes cannot be determined from this chunk.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The setup command pipes a mutable remote script directly into Bash without verifying its integrity or reviewing its contents; the PowerShell alternative has the same weakness. A compromised distribution endpoint or release pipeline could execute arbitrary code with the invoking user's permissions, exposing local data and credentials. Its legitimate dependency-setup purpose and missing-CLI precondition reduce exposure but do not eliminate the supply-chain risk.

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.
