Plausible Analytics

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent Plausible Analytics connector, but its first-time setup tells the agent to install a remote CLI with a curl-to-shell command without integrity checks or explicit user approval.

Install only if you are comfortable with OOMOL mediating access to your Plausible Analytics account. Prefer installing the oo CLI yourself from official documentation, review the installer before running it, and confirm any write action payload before allowing the skill to record analytics events.

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

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

  ```

Finding
The skill instructs the agent to execute a remote installer via `curl ... | bash`, which fetches code from the network and immediately runs it without integrity verification, pinning, or user review. In an agent skill context, this is especially dangerous because a missing CLI binary could trigger the fallback path, leading to arbitrary code execution on the host if the remote script is compromised, tampered with, or unexpectedly changed.
