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 alerts mistake Markdown fences, inline identifiers, and TypeScript template literals for shell execution. The network, path, and environment examples are normal frontend patterns. One semantic issue remains: the authentication examples persist bearer tokens in browser storage, where injected scripts could read them.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:354-359SKILL.md:392-408
Insecure Browser Token Persistence
The examples read a bearer token from localStorage and persist the authentication token through Zustand. A successful XSS attack could extract the token.
The code directly reads localStorage for an Authorization header and configures Zustand persistence for the token. Browser scripts can access this storage.

Remediation

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

  1. FIX-001
    Medium
    The authentication templates read and persist bearer tokens in browser storage.
    Prefer Secure, HttpOnly, SameSite cookies or short-lived in-memory tokens, and document the required CSRF and XSS protections.

Expert evidence

Immutable subject identity, scanner metadata, dismissed matches, and source-level evidence.
