Headline
GHSA-w387-5qqw-7g8m: Content-Security-Policy header generation in middleware could be compromised by malicious injections
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.
