TiMEM Space

Security checks for vulnerabilities and agentic risk

Overview

The skill is purpose-aligned overall, but its fallback setup tells an agent to run an unverified remote installer script.

Review this skill before installing. It appears designed for legitimate TiMEM Space use, but only run the CLI installer after independently checking the official OOMOL installation instructions and approving the install yourself. Be careful with actions that create, overwrite, or delete TiMEM Space memories or other account data.

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 the agent to install software by piping a remote script directly into a shell (curl ... | bash). This bypasses integrity verification, makes the executed code dependent on the current contents of a third-party URL, and creates a supply-chain/RCE risk if the host, transport, or distribution pipeline is compromised. In this skill context, the danger is elevated because the content explicitly tells an automation agent when to run the command during fallback setup, which could lead to unattended execution.
