Security audit

Gangtise

Security checks for vulnerabilities and agentic risk

Overview

The data-reading workflow fits its purpose, but setup tells the agent to execute downloaded code without verification or a clear user approval step.

Review the setup behavior before installing. Install a reviewed, version-specific oo release yourself or require approval and verification before the agent runs an installer. Gangtise requests use your OOMOL-connected account, so review its permissions and billing. The bundled instructions show no malicious behavior, but the remote installer's effects 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
  • 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
96% confidence
Finding

The supplied chunk executes an external installer rather than implementing the declared search-and-read behavior. Dependency installation can be a supporting implementation detail, but nothing supplied establishes this installer's role in accessing Gangtise. The downloaded script is not provided, so its further behavior and any maliciousness cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a live HTTPS response directly into bash executes mutable remote code without a pinned version, independently verified integrity, or an inspection step; the PowerShell alternative has the same problem. The domain is relevant to the documented dependency, but compromise of its hosting or release pipeline could still result in arbitrary code execution with access to local files and credentials.

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

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The missing-CLI fallback instructs the agent to execute downloaded shell or PowerShell code without first obtaining approval for local code execution and installation changes. Although this is a legitimate dependency-setup context, a request to read financial data does not necessarily authorize installing software, and a compromised installer could execute with the invoking user's permissions.

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.
