Highest confirmed finding severity

High

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.

The static hits are false positives from Markdown examples that show environment-based configuration and inline code paths. One semantic issue remains: the OAuth callback example redirects with an access token in a query string, which can leak through history, logs, and referrers.

Risk findings

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

Confirmed security concerns (1)

RISK-001 High
resources/implementation-playbook.md:329
Access Token Exposed in OAuth Redirect URL
The OAuth callback example redirects to the frontend with token=${tokens.accessToken} in the query string. Access tokens in URLs can leak through browser history, logs, analytics, and referrer headers.
The code sample directly places the generated access token in the redirect URL. This is a well-known token exposure risk in OAuth callback handling.

Remediation

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

  1. FIX-001
    High
    OAuth callback example places an access token in a redirect URL.
    Use an authorization code exchange or set a secure HttpOnly SameSite cookie. Keep tokens out of query strings, logs, and referrer headers.
  2. FIX-002
    Low
    Secret examples rely on non-null environment variable assertions.
    Add startup validation for required secrets and document secret manager usage. Fail closed when JWT, session, Redis, or OAuth settings are missing.

Expert evidence

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