HoneyHive

Security checks for vulnerabilities and agentic risk

Overview

The HoneyHive workflow is coherent, but its setup instructions can execute unverified downloaded code without separate user approval.

Review and approve CLI installation separately, using a verified version and checking its effects on installed agent skills. OOMOL mediates HoneyHive access and receives action payloads. Keep the skill's explicit approvals for writes and deletion. The bundled skill was fully inspected, but downloaded installer contents and the credential-handling 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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command executes an external installer and shows no HoneyHive interaction. Nothing in the supplied material establishes Oomol installation as a supporting requirement for HoneyHive, so this is an undeclared capability involving an inconsistent resource. The downloaded script's further behavior cannot be determined from this chunk.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command pipes a mutable remote script directly into bash without version pinning, integrity verification, or review. A compromised installer host or release pipeline could therefore execute arbitrary code with the agent's local privileges; HTTPS protects transport but does not establish that the script itself is trustworthy.

The setup workflow executes downloaded installer scripts without warning about local code execution and system changes.

Medium
Category
Output Handling
Confidence
93% confidence
Finding

The fallback instructs the agent to execute downloaded shell or PowerShell code without explicitly obtaining approval for local installation and system changes. Although triggered only when the CLI is missing, this expands a HoneyHive data request into local code execution with the agent's privileges, and the write-confirmation rules cover HoneyHive state rather than this installation.

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.
