Memory Vault

Security checks for vulnerabilities and agentic risk

Overview

This skill transparently provides persistent cloud memory for agents, but users should avoid storing secrets or sensitive data unless they trust the service and its retention controls.

Install only if you want agent memory stored in the provider's cloud service. Do not store credentials, tokens, regulated data, private prompts, or sensitive project material unless you have reviewed and trust the provider's retention, deletion, and access-control practices.

A.I.G

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

Missing User Warnings

Medium

Finding
The skill explicitly advertises persistent cloud storage for agent notes, state, and vector fragments, but it does not warn users that potentially sensitive prompts, secrets, or personal data may be transmitted to and retained by a third-party service. In an agent setting, this omission is security-relevant because autonomous workflows may store data automatically, creating a realistic risk of unintended long-term retention and cross-session exposure.
