Summary
Content-Security-Policy header generation in middleware could be compromised by malicious injections
Details

Impact

When the following conditions are met: - Automated CSP headers generation for SSR content is enabled - The web application serves content that can be partially controlled by external users

Then it is possible that the CSP headers generation feature might be "allow-listing" malicious injected resources like inlined JS, or references to external malicious scripts.

Patches

Available in version 1.3.0 .

Workarounds

  • Do not enable CSP headers generation.
  • Use it only for dynamically generated content that cannot be controlled by external users in any way.
