PDF Vector

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent PDF Vector connector, with the main caution being a disclosed one-time remote installer command for the required oo CLI.

Install only if you are comfortable using OOMOL as the intermediary for PDF Vector. The normal actions are read-oriented, but they send public document URLs and requested schemas/questions through the connector. For first-time setup, review the oo CLI installer source or use the vendor's documented install method instead of blindly piping a remote script into a shell.

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

Finding

The skill explicitly instructs users to install software by piping a remote script directly into bash, which is a well-known supply-chain and arbitrary-code-execution risk. If the installer endpoint, transport, hosting, or upstream release process is compromised, a user following the skill could execute attacker-controlled code on their machine.
