Security audit

Daytona

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly matches its Daytona management purpose, but its setup path tells the agent to run an unverified remote installer on the user's machine.

Review the setup instructions before installing. Prefer installing the oo CLI through a verified package manager or documented installer with integrity checks, and only allow write or destructive Daytona actions after confirming the exact sandbox and effect.

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

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill instructs the agent to execute a remote installer via 'curl ... | bash', which pipes network-fetched code directly into a shell without verification. If the remote server, transport, or script is compromised, this can lead to arbitrary code execution on the host running the skill.

Finding

The trigger phrase 'Use this skill for ANY Daytona request' is overly broad and can cause the agent to invoke this skill for vague mentions of Daytona, not just explicit user requests to operate Daytona resources. Because the skill includes write and destructive actions, over-invocation increases the chance of unintended state changes or unnecessary exposure to risky operational paths.
