Security audit

Eraser

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for managing Eraser through OOMOL, but its fallback setup tells an agent to run remote install scripts directly, which is high-impact local execution without verification.

Install only if you are comfortable using OOMOL as an intermediary for your Eraser account. Avoid letting an agent run the pasted curl-to-bash or iex installer automatically; install the oo CLI through verified official steps, then review and approve any write or destructive Eraser action before it runs.

External Script Fetching

Category
Supply Chain
Confidence

Finding

The skill instructs the agent to install software via a remote script piped directly into bash, which executes network-fetched code without prior verification. If the install endpoint, transport, or upstream distribution is compromised, this can lead to arbitrary code execution on the host running the skill.

Finding

The skill description says to use this skill for ANY Eraser request, which is overly broad and can cause the agent to invoke it whenever Eraser is merely mentioned rather than when its use is clearly intended. In a skill that supports reads, writes, and destructive operations, this ambiguity increases the chance of unintended tool execution and unnecessary exposure to state-changing capabilities.
