Summary

When using http.CrossOriginProtection, the AddInsecureBypassPattern method can unexpectedly bypass more requests than intended. CrossOriginProtection then skips validation, but forwards the original request path, which may be served by a different handler without the intended security protections.

Risk Assessment

The risk is that requests that should be checked by CrossOriginProtection may be handled by another component without proper security, potentially leading to unauthorized access or integrity compromise.

Recommendation

It is recommended to review the configuration of AddInsecureBypassPattern and ensure it does not cover too broad a range of requests. Also test the behavior of CrossOriginProtection after changes and consider updating to a patched version.
