Merge Risk: Medium

This is a minor version upgrade for undici that primarily includes security fixes and protocol hardening. While there are no API removals, the changes introduce stricter validation that could impact existing code.

Key Changes:

  • Stricter Header Validation: The library now performs stricter validation on header values to prevent potential CRLF injection vulnerabilities. Requests with malformed header values that were previously accepted may now be rejected.
  • Interceptor Fixes: The retry interceptor now correctly handles Content-Length to prevent potential response desynchronization.

Potential Impact:
Applications that inadvertently send invalid headers or rely on the previous, more lenient parsing behavior may experience new errors after this upgrade. This is a behavioral change that requires verification.

Recommendation:
Review and test any code that generates or forwards HTTP headers to ensure compliance with standard formats. Pay close attention to retry logic if you use custom interceptors.
