Latchshot

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly does what it says, but its first-time setup includes direct remote-script execution to install a CLI, which should be reviewed carefully before use.

Before installing, use a safer `oo` CLI installation path if available: prefer a signed package or official install guide, inspect any downloaded installer before running it, and do not let the skill perform write actions such as `capture_page` until you have confirmed the exact payload and effect.

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 remotely fetched script directly into a shell (curl ... | bash). This creates a code-execution path where a compromised host, CDN, DNS resolution, TLS interception failure, or upstream account compromise could cause arbitrary commands to run on the user's machine without review. In this skill context, the danger is elevated because the content is framed as a fallback troubleshooting step the agent may relay or run when oo is missing.
