PayPal

Security checks for vulnerabilities and agentic risk

Overview

This PayPal skill is mostly coherent, but it asks the agent to run an unverified remote installer and it has broad financial-account authority.

Install only if you trust OOMOL and are comfortable with the oo CLI having access to your connected PayPal workflow. Before using the setup commands, review or install the CLI through a verified method rather than blindly piping a remote script into a shell, and require explicit approval for payments, refunds, captures, tracking changes, or voids.

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

Finding

The skill instructs the agent to install the CLI by piping a remotely fetched script directly into a shell, which is a classic supply-chain and remote-code-execution risk. If the install endpoint, transport, or upstream distribution is compromised, arbitrary code could run on the host with the agent's privileges.

Finding

The skill description says to use this skill for ANY PayPal request, which is an overly broad trigger that can cause the agent to invoke this skill for all PayPal-related tasks without sufficient narrowing. In a payment context, that increases the chance of unintended use of write or destructive actions and can bypass safer, more task-specific handling or confirmation flows.
