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 static backtick findings are Markdown examples, table values, endpoint names, or prompt samples rather than Ruby shell execution. The skill relies on local RunComfy CLI commands and a RunComfy API request with a bearer token. No prompt injection attempt or malicious exfiltration intent was found.

Report position

SKILL.md:10
Ruby/shell backtick execution
Calls `runcomfy run happyhorse/happyhorse-1-0/text-to-video` through
The skill documentation intentionally directs the agent or user to run the local RunComfy CLI. External CLI execution can affect the host and submit data externally, so it requires user awareness and constrained arguments.
Medium
SKILL.md:24-26
Ruby/shell backtick execution
```bash
The fenced example runs npx to add a skill from a GitHub source. That is real external command execution with package and supply-chain exposure.
Medium
SKILL.md:44-45
Ruby/shell backtick execution
1. **RunComfy CLI** — `npm i -g @runcomfy/cli`
The prerequisite tells users to install the RunComfy CLI globally through npm. Global CLI installation is legitimate but has package supply-chain and host modification risk.
Medium
SKILL.md:45-46
Ruby/shell backtick execution
2. **RunComfy account** — `runcomfy login` opens a browser device-code flow.
The prerequisite directs users to run runcomfy login, which opens an authentication flow and creates local credentials. That is expected but still a security-relevant command.
Medium
SKILL.md:65-69
Ruby/shell backtick execution
```bash
The fenced example runs runcomfy with user-controlled prompt content and an output directory. The command is fixed, but it invokes a local CLI with network and filesystem effects.
Medium
SKILL.md:73-82
Ruby/shell backtick execution
```bash
The fenced example runs runcomfy with user-controlled prompt content and an output directory. The command is fixed, but it invokes a local CLI with network and filesystem effects.

SKILL.md:86-90
Ruby/shell backtick execution

The fenced example runs runcomfy with user-controlled prompt content and an output directory. The command is fixed, but it invokes a local CLI with network and filesystem effects.

Ruby/shell backtick execution
1. The skill invokes `runcomfy run happyhorse/happyhorse-1-0/text-to-video` with a JSON body matchin
The skill documentation intentionally directs the agent or user to run the local RunComfy CLI. External CLI execution can affect the host and submit data externally, so it requires user awareness and constrained arguments.
Low
SKILL.md:179
Hardcoded URL
2. The CLI POSTs to `https://model-api.runcomfy.net/v1/models/happyhorse/happyhorse-1-0/text-to-vide
The documented workflow posts requests to the RunComfy Model API using a bearer token. This is intentional network behavior, but it exposes prompts and credentials to a third-party service.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:178-181
Third-Party Prompt and Token Transfer
The workflow sends user prompts to the RunComfy Model API and authenticates with a bearer token. Users should understand that prompt content leaves the local environment.
Lines 178-181 describe CLI submission, a POST to the RunComfy API with the bearer token, polling, and result retrieval. This is explicit third-party data transfer, not inferred behavior.

Remediation

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

  1. FIX-001
    Medium
    External CLI execution
    Ask for explicit user approval before running install, login, or generation commands. Keep command arguments fixed and validate output directories before use.
  2. FIX-002
    Medium
    Third-party prompt transfer
    Clearly disclose that prompts and generated output requests are sent to RunComfy. Let users review sensitive prompt text before submission.
  3. FIX-003
    Medium
    Unpinned package installation guidance
    Prefer pinned CLI versions or official installation instructions so users can verify the package they install.
  4. FIX-004
    Low
    Local API token storage
    Document token file removal, logout behavior, and the environment variable alternative for temporary or containerized sessions.
