Risks

Inadvertent Caching of Sensitive Headers [Medium]

The addition of X-More-Headers to the AWS CloudFront response headers policy could potentially include sensitive data that should not be cached. Analyzing the current state of the cloudfront-response-headers-policy, it is unclear what kind of data X-More-Headers will carry and if sensitive information is at risk. Without knowing the exact content and intention behind X-More-Headers, this change could lead to unintended caching of sensitive data, violating privacy policies and potentially exposing it to end users.

Misconfiguration of CORS Policy [Low]

Modifying the access_control_allow_headers by appending X-More-Headers might affect the CORS policy given the current setup of the cloudfront-response-headers-policy. The CORS headers defined are crucial for resource sharing between different origins. Improper configuration here may disrupt client application interactions that depend on CORS. The impact on the application's functionality cannot be estimated without understanding the interactions between the added headers and client applications.

Increased Response Header Size [Low]

The updated configuration will increase the size of the response headers by adding a new header (X-More-Headers). Although the impact might be minimal, it is possible that a significantly large or unoptimized header could have performance implications, especially if the content served by CloudFront requires frequent fetching. Evaluating the average size and necessity of X-More-Headers is suggested before deploying this change.

Impact on Upstream Services due to Additional Headers [Low]

Adding X-More-Headers to the CloudFront response headers could affect the behavior of upstream services or APIs. Depending on the design of these services, they may not be prepared to handle additional headers, leading to processing issues or errors. Without adequate validation in the service configurations to ensure they expect or properly ignore the new headers, the stability of these services could be at risk.
