Memento Database

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Memento Database connector that discloses its read, write, and delete abilities and requires confirmation for state-changing actions.

Install only if you intend to let the agent access your connected Memento Database account. Review any write or delete payload before approval, and verify the OOMOL CLI installer through official documentation before running the pipe-to-shell setup command.

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

Finding

The skill instructs users to install the CLI via a remote script piped directly to bash, which is a classic supply-chain and remote code execution risk. If the install endpoint, TLS trust chain, distribution channel, or upstream host is compromised, arbitrary code will execute immediately on the user's machine.

Finding

The description says to use this skill for ANY Memento Database request and instead of calling the API directly, which can cause over-selection of this skill without sufficient task scoping or user-intent checks. In an agent environment, broad routing language increases the chance that read, write, or destructive database operations are invoked automatically when a safer or narrower path should have been chosen.
