Highest confirmed finding severity

High

2 confirmed security findings require attention.

Installation context

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Most static findings are false positives caused by Markdown fences, placeholders, local addresses, and ordinary setup references. Confirmed risks include mutable remote installers, root execution, Docker group privileges, and exposed default database credentials. No prompt injection or data-exfiltration intent was found.

Report position

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Capability review items (8)
High
SKILL.md:106
sudo privilege escalation
sudo -E bash "$tmpdir/nodesource-setup.sh"
This runs a downloaded NodeSource script with root privileges and preserves the environment. A compromised response or dependency could modify the entire system.
High
SKILL.md:271
sudo privilege escalation
sudo sh get-docker.sh
This executes the mutable get.docker.com script as root without an integrity check or review step. Compromise of the download path would yield system control.
High
SKILL.md:274
sudo privilege escalation
sudo usermod -aG docker $USER
Adding a user to the docker group grants control of the Docker daemon. That access is commonly equivalent to root privileges on the host.
High
SKILL.md:300
Database connection strings
- DATABASE_URL=postgresql://postgres:password@db:5432/mydb
The example embeds the predictable database password "password" and publishes PostgreSQL on the host. Reuse outside an isolated machine could expose the database.
Medium
SKILL.md:90
Unix shell invocation
/bin/bash "$tmpdir/homebrew-install.sh"
This command executes a script downloaded from a mutable URL. Manual review reduces risk, but remote shell code can still compromise the user account.
Low
SKILL.md:88
Hardcoded URL
curl -fsSLo "$tmpdir/homebrew-install.sh" https://raw.githubusercontent.com/Homebrew/install/HEAD/in
The command downloads a mutable installer from GitHub for later execution. The official host lowers suspicion, but no version pin or checksum protects integrity.
Low
SKILL.md:104
Hardcoded URL
curl -fsSLo "$tmpdir/nodesource-setup.sh" https://deb.nodesource.com/setup_20.x
The command downloads a mutable NodeSource setup script that is later executed as root. No version pin or checksum authenticates the retrieved content.
Low
SKILL.md:270
Hardcoded URL
curl -fsSL https://get.docker.com -o get-docker.sh
The command downloads a mutable Docker installation script that is immediately executed as root. It provides no checksum or content review step.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (2)

RISK-001 High
SKILL.md:300-314
Default Database Credentials Exposed on Host Port
The Docker Compose example publishes PostgreSQL on port 5432 while assigning the password "password". Other local users or reachable hosts could authenticate.
The configuration directly combines predictable credentials with a published database port. The risk is clear unless the host network is fully isolated.
RISK-002 Medium
SKILL.md:446-463
Setup Template Runs Project-Defined Code Without Confirmation
The setup template runs npm installation, migrations, and setup tests automatically. Dependency lifecycle hooks or project scripts can execute arbitrary code and alter data.
The listed commands execute dependency and project-controlled scripts without a review or confirmation boundary. Their exact behavior depends on the target repository.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    High
    Mutable remote installer scripts are downloaded and executed, including with root privileges.
    Pin installer versions, verify published checksums or signatures, show the reviewed artifact, and request explicit confirmation before execution.
  2. FIX-002
    High
    The Docker instructions add the user to a root-equivalent daemon group.
    Prefer rootless Docker, explain the privilege impact, and require explicit user approval before changing group membership.
  3. FIX-003
    High
    The Compose example publishes PostgreSQL with the password "password".
    Generate a unique development password, bind the port to loopback, or omit host publishing when external access is unnecessary.
  4. FIX-004
    Medium
    The setup template runs dependency hooks, migrations, and repository scripts automatically.
    Separate checks from changes, inspect package scripts, and request confirmation before installation, migrations, or project-defined commands.
