Honeybadger

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for using Honeybadger through OOMOL, but its setup instructions tell an agent to run a remotely fetched installer script without checksum verification or explicit user approval.

Review the OOMOL CLI installation path before installing. Prefer installing oo from verified official documentation with pinned releases or checksum/signature verification, and do not let an agent run the curl-to-shell or PowerShell iex installer automatically. Once oo is installed and Honeybadger is connected, confirm exact payloads before any write actions are run.

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

External Script Fetching

Category
Supply Chain
Content
- **`oo: command not found`** — install the oo CLI (other platforms: <https://cli.oomol.com/install-guide.md>):

  ```bash
  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  ```

  ```powershell

Finding
The skill instructs the agent to install software by piping a remotely fetched script directly into a shell, which is a classic supply-chain and remote code execution risk. Because this appears in an agent skill, an automated system could execute it with little scrutiny when `oo` is missing, turning a setup failure into arbitrary code execution from a third-party host.
