Security checks for vulnerabilities and agentic risk
Overview
The skill matches its MuAPI utility purpose, but its recommended setup can expose a MuAPI API key in command history and process arguments.
Before installing, prefer the interactive setup form, avoid typing the API key directly into a command, check where the muapi CLI stores credentials, and rotate any key previously entered through the documented command-line example.
Vulnerability Patterns
- Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
- 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

- Finding
The markdown instructs users to provide and store an API key and to test it, but it does not include any user-facing warning about credential sensitivity, storage location, or the privacy/security implications of exposing or persisting the key. Under the markdown criteria for missing user warnings, credential-related behavior should be disclosed when it could affect user data or privacy.
