Lethe Memory
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed persistent-memory integration with bounded Lethe tools and no evidence of hidden execution or unrelated data access.
Install this only if you want the agent to retain durable work memory across sessions. Configure the Lethe endpoint and API key through the plugin or protected secret storage, review what gets recorded, and do not use it for secrets or sensitive credentials.
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
