Security audit

TheHive

Security checks for vulnerabilities and agentic risk

Overview

TheHive actions have clear approval controls, but the setup path can execute unverified code and introduce persistent changes to other agents.

Review and install the CLI separately before use, and disable its automatic skill synchronization if you do not want changes across your agents. Connect only the TheHive permissions you need and consider whether incident data may pass through OOMOL. The skill requires approval for TheHive writes; the review concern is the broader setup behavior. External installer and service implementations were not verified.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied chunk performs remote script installation and contains no visible TheHive operations. Nothing provided establishes that this installer is a supporting dependency for TheHive functionality. The downloaded script's further behavior cannot be determined from this chunk.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The setup command pipes a remotely retrieved, mutable script directly into Bash without verifying a pinned version, trusted signature, or checksum; the PowerShell alternative has the same weakness. If the distribution endpoint or release pipeline is compromised, the installer can execute attacker-controlled code with the invoking user's privileges, potentially exposing local credentials and files. The missing-CLI condition limits exposure but does not remove this 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.
