Highest confirmed finding severity

Critical

3 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.

The audit found no prompt-injection content or hidden data-exfiltration intent in SKILL.md. Most static hits are Markdown fences, sample Bun server handlers, environment variable examples, or documentation links. Confirmed risks are pipe-to-shell install commands and a non-default npm registry example.

Report position

Latest published report

Latest refers to the report sequence, not to artifact currentness.

Audit attestation

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.

  1. Source

    Commit and path bound

  2. Artifact

    Content and tree hashes bound

Capability review items (4)
High
SKILL.md:31
PowerShell invocation
powershell -c "irm bun.sh/install.ps1 | iex"
The Windows install example invokes PowerShell and executes a remote install script through iex. This can run unreviewed code on the user system.
High
SKILL.md:147
Hardcoded URL
bun add lodash --registry https://registry.npmmirror.com
The URL selects a third-party npm mirror with --registry, changing package trust boundaries. This is a real supply-chain exposure even though shown as an example.
Low
SKILL.md:28
Hardcoded URL
curl -fsSL https://bun.sh/install | bash
The URL is used in a curl pipe-to-shell install command, which downloads remote code for execution. The official source lowers malicious intent but not remote execution risk.
Low
SKILL.md:586
Hardcoded URL
curl -fsSL https://bun.sh/install | bash
The URL is used in a curl pipe-to-shell install command, which downloads remote code for execution. The official source lowers malicious intent but not remote execution risk.

Risk findings

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

Confirmed security concerns (3)

RISK-001 Critical
SKILL.md:28
Pipe to shell pattern
curl -fsSL https://bun.sh/install | bash
The command pipes a remote install script directly into bash. This is a real remote code execution risk if the network, script, or source is compromised.
RISK-002 Critical
SKILL.md:586
Pipe to shell pattern
curl -fsSL https://bun.sh/install | bash
The command pipes a remote install script directly into bash. This is a real remote code execution risk if the network, script, or source is compromised.
RISK-003 High
SKILL.md:147
Non-standard NPM registry
bun add lodash --registry https://registry.npmmirror.com
The example installs from registry.npmmirror.com instead of the default npm registry. Changing registries can introduce dependency confusion and supply-chain trust risk.

Remediation

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

  1. FIX-001
    Critical
    Remote install scripts are piped directly into bash.
    Replace pipe-to-shell examples with package manager installs, checksum verification, or instructions to inspect the script before execution.
  2. FIX-002
    High
    The Windows install example executes a remote PowerShell script through iex.
    Prefer a verified installer or package manager command, and warn users before executing remote PowerShell content.
  3. FIX-003
    High
    A dependency example uses a non-default npm registry mirror.
    Remove the mirror example or clearly state that users should only use trusted registries with integrity controls.
