Content-Security-Policy

Content-Security-Policy failed at "Evaluate fetch baseline".

50 Fail

Needs attention

Content-Security-Policy

Failed check
01

Issue

CSP does not define default-src; several fetch directives may have no restrictive fallback.

02

Why it matters

Content Security Policy reduces the impact of injection bugs by limiting where scripts, styles, frames, forms, and other browser resources can load or execute.

Check name

Score

Status

Category

Security & Trust

Maturity

Established

Goal

Constrain browser resource loading and script execution with an enforcing Content-Security-Policy header.

Result

Content-Security-Policy failed at "Evaluate fetch baseline".

Validation steps

  1. Evaluate fetch baseline

    CSP does not define default-src; several fetch directives may have no restrictive fallback.

  2. Evaluate script execution

    No script-src or default-src directive constrains script execution.

  3. Review hardening directives

    CSP is missing recommended hardening directives: object-src, base-uri, form-action.

  4. Review CSP reporting

    CSP does not define a reporting endpoint.

Failed check
01

Issue

One or more DNS-AID records could not be parsed as usable HTTPS/SVCB ServiceMode records.

Details

02

Why it matters

DNS-AID lets agents discover index, A2A, and other agent entrypoints before fetching HTTP metadata. HTTPS/SVCB records provide the service-binding substrate, while DNSSEC can authenticate the discovery answer when available.
