Security audit

Triple Whale

Security checks for vulnerabilities and agentic risk

Overview

The data-reading workflow fits its purpose, but setup directs your agent to execute an unverified downloaded installer without a separate approval step.

Prefer a reviewed, preinstalled CLI and require approval before running downloaded installers. Review its automatic skill synchronization and disable it if unwanted. Triple Whale requests and returned business/customer data pass through OOMOL. The installer contents and hosted connector implementation 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
97% confidence
Finding

The supplied chunk performs remote script execution rather than searching or reading Triple Whale data. It shows no Triple Whale interaction or connection establishing this installer as a supporting dependency. The downloaded script's contents are not supplied, so its further behavior cannot be assessed.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a remotely fetched installer directly into bash executes mutable network content without an independent integrity check; the PowerShell alternative has the same issue. If the distribution endpoint or delivery chain is compromised, attacker-controlled code could run with the agent's local privileges and access files or credentials, although the missing-CLI condition and any enforced oo-only tool restriction limit reachability.

Content

The setup workflow instructs the agent to execute downloaded installer scripts without warning about local system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The fallback directs the agent to install software after a missing-command error without explicitly obtaining approval for local changes or explaining that downloaded code will execute. Restricting installation to first-time setup reduces exposure, but a data-reading request does not itself authorize local software installation; the declared oo-only tool allowance may prevent execution if strictly enforced.

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.
