Highest confirmed finding severity

Medium

1 confirmed security finding requires 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 external-command detections are Markdown formatting, code fences, or source examples and are false positives. Eight examples invoke external tooling, one image loads remotely, and the workflow sends supplied code and props to inference.sh.

Capability review items (9)
Medium
SKILL.md:7
Ruby/shell backtick execution
> **Install the belt CLI skill:** `npx skills add belt-sh/cli`
The line instructs users to run npx to download and install a third-party skill. This creates command-execution and supply-chain exposure.
Medium
SKILL.md:19-30
Ruby/shell backtick execution
```bash
The Bash example runs belt login and belt app run. These commands use an authenticated external CLI and submit a rendering job.
Medium
SKILL.md:72-80
Ruby/shell backtick execution
```bash
The Bash block invokes belt app run with supplied TSX. It executes an external CLI and sends a remote rendering request.
Medium
SKILL.md:84-92
Ruby/shell backtick execution
```bash
The Bash block invokes belt app run with supplied TSX. It executes an external CLI and sends a remote rendering request.
Medium
SKILL.md:96-98
Ruby/shell backtick execution
```bash
The Bash block invokes belt app run with supplied TSX. It executes an external CLI and sends a remote rendering request.
Medium
SKILL.md:108-117
Ruby/shell backtick execution
```bash
The Bash block invokes belt app run with supplied TSX and props. It executes an external CLI and submits data remotely.
Medium
SKILL.md:121-129
Ruby/shell backtick execution
```bash
The Bash block invokes belt app run with supplied TSX. It executes an external CLI and sends a remote rendering request.
Medium
SKILL.md:190-205
Ruby/shell backtick execution
```bash
The Bash block runs several npx skill installation commands. These commands download external content and create supply-chain exposure.

SKILL.md:13
Hardcoded URL
![Remotion Render](https://cloud.inference.sh/app/files/u/4mg21r6ta37mpaz6ktzwtt8krr/01kg2c0egyg243m
The Markdown image references a remote inference.sh asset. Rendering the documentation can contact that host and disclose viewer network metadata.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:23-29SKILL.md:138-167
Remote Submission of User Code and Props
The examples submit TSX source and optional props to inference.sh for remote rendering. Sensitive source or props would leave the local environment.
Both CLI and Python examples explicitly send code in an input object to infsh/remotion-render. This is the documented core workflow.

Remediation

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

  1. FIX-001
    Medium
    The workflow submits user code and props to an external rendering service.
    Require explicit approval before submission and warn users to remove secrets or confidential data from source and props.
  2. FIX-002
    Medium
    Installation examples use npx skill commands without pinned versions or immutable references.
    Pin trusted package and skill versions, document their source, and require confirmation before installation.
  3. FIX-003
    Low
    The documentation embeds an image from a remote inference.sh URL.
    Bundle the image with the skill or clearly disclose that viewing the documentation can contact the remote host.
