Security audit
Silence Removal and Audio Cleanup
Security checks for vulnerabilities and agentic risk
Overview
The skill provides clearly disclosed instructions for cleaning up audio through an external editing service, with no hidden or unrelated behavior found.
Use media you are comfortable sharing with Levea and exposing through public URLs. Protect your API key, verify the separately installed integration, and enable requirePlanApproval if you want to review edits first. Both scanners reported no findings; this review covers the supplied instructions, not the external service's implementation or data-retention practices.
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
Vulnerability Patterns
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
