Highest confirmed finding severity

Medium

2 confirmed security findings require attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

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

Static analysis found many command and URL patterns in SKILL.md. Review confirmed most shell backtick and weak crypto hits are markdown or wording false positives, but the remote installer and infsh rendering workflow are real elevated-risk behaviors that require user warning. No evidence found of prompt injection, credential exfiltration, persistence, or confirmed malicious intent.

Confirmed security concerns (2)

RISK-001 Medium
SKILL.md:17SKILL.md:29
Remote Installer Piped to Shell
TRUE_POSITIVE: The quick start tells users to run a remote install script with curl piped directly to sh. This is dangerous because script contents can change after review and execute with the user's local privileges. The install note describes checksum verification, but the pipe-to-shell command still requires trust in the remote endpoint.
The exact pipe-to-shell pattern is present and semantically executes a remote installer. Confidence is high on the risk, although the surrounding text indicates legitimate installation intent rather than malware.
RISK-002 Medium
SKILL.md:4SKILL.md:20-26SKILL.md:70-77SKILL.md:82-89SKILL.md:94-101SKILL.md:106-114SKILL.md:119-126
External CLI Sends Render Jobs to Remote Service
TRUE_POSITIVE: The skill allows Bash access for infsh commands and documents infsh app run calls that submit TSX component code and props to inference.sh. This is the intended function, but it can expose proprietary code, rendered assets, or prompt-provided data to a third-party service.
The allowed tool declaration and repeated remote run examples clearly show external command and network behavior. The risk is moderate because the behavior is disclosed and central to the skill's purpose.

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

SKILL.md:15-27SKILL.md:70-78SKILL.md:82-90SKILL.md:94-102SKILL.md:106-115SKILL.md:119-127SKILL.md:131-168SKILL.md:172-184SKILL.md:188-203
Markdown Backtick Command Flags Are Documentation Examples
FALSE_POSITIVE: Most shell execution findings point to fenced bash, tsx, or python examples in documentation. These snippets demonstrate how to call the remote renderer and are not hidden Ruby backtick execution inside a runtime script.
The flagged locations are inside markdown code fences or inline code examples. They are visible documentation, not concealed executable skill code.
Low
SKILL.md:3SKILL.md:29SKILL.md:33
Weak Cryptography Alerts Are Text Matching False Positives
FALSE_POSITIVE: The weak cryptographic algorithm alerts do not identify use of MD5, SHA-1, DES, or another weak primitive. The relevant security text says SHA-256 checksum verification, and other hits appear to come from ordinary words such as description.
Line 29 references SHA-256, which is not a weak checksum for this purpose. The other cited lines do not contain cryptographic operations.
Low
SKILL.md:9-11SKILL.md:207-209
Hardcoded URLs Are Mostly Documentation and Asset Links
FALSE_POSITIVE: The non-installer URLs point to the inference.sh website, an image asset, Remotion documentation, and inference.sh documentation. No evidence found that these links exfiltrate secrets or contact unrelated infrastructure.
The URLs are visible documentation or asset references that match the skill's stated service. The installer URL is handled separately as a medium finding.
