Security checks for vulnerabilities and agentic risk

Overview

This Reddit skill is coherent and disclosed, with user confirmation required for posting, editing, or deleting, though users should manually review the CLI installer before running it.

Install only if you are comfortable routing Reddit actions through OOMOL’s connector. Review the oo CLI installer source or use an official/manual install path before running the provided pipe-to-shell commands, and approve any post, edit, or delete payload carefully.

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

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill instructs the agent to install software by piping a remote script directly into bash, which is a classic supply-chain risk and enables arbitrary code execution if the remote host, transport, or script content is compromised. In a skill context, this is more dangerous because the content normalizes an unsafe installation pattern that an automated agent may execute without independent verification.

Vague Triggers

Confidence
96% confidence
Finding

The skill description says to use this skill for ANY Reddit request and instead of calling the API directly, which is an overly broad trigger that can cause the agent to invoke a state-changing skill in situations where a narrower read-only or more specialized path would be safer. Because the skill includes write and destructive actions, broad activation increases the chance of unintended use, parameter confusion, or accidental execution of sensitive Reddit operations.
