DocuSeal

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent DocuSeal connector, but its setup instructions include unverified remote installer commands that can execute changing code on a user's machine.

Review the installer path before using this skill. Prefer installing the oo CLI from a versioned, verifiable source or inspect and verify the downloaded installer before running it. For normal use, confirm any DocuSeal write action payload before execution.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill instructs the agent to install software by piping a remotely fetched script directly into bash. This is dangerous because it executes unverified code from the network without integrity checking, so a compromised server, CDN, or MITM in a misconfigured environment could achieve arbitrary code execution on the host.

Finding

The description says to use this skill for "ANY DocuSeal request" and "Whenever a task involves DocuSeal," which is a very broad activation condition. It does not define narrower trigger phrases, boundaries, or exclusions, increasing the chance of unintended invocation for casual mentions or indirect references to DocuSeal.
