Security audit

Evenium

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent Evenium read-only connector, but its setup instructions can cause an agent to install a remote CLI script automatically if the CLI is missing.

Before installing, confirm you trust OOMOL and its oo CLI distribution path. Do not allow the agent to run the curl-to-bash or PowerShell installer automatically; install the CLI through a verified method and review what Evenium event and guest data the connected account can access.

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

Finding

The skill instructs the agent to install software via curl ... | bash, which executes a remote script without prior verification. If the hosting source, transport, or upstream distribution is compromised, this can lead to arbitrary code execution on the user's machine under the current user's privileges.

Finding

The description says to use this skill for "ANY Evenium request" and "Whenever a task involves Evenium," which is an extremely broad activation condition. It does not define boundaries, exclusions, or negative examples, so the skill could be invoked for loosely related everyday requests that merely mention Evenium.
