Bref Multiple Value Headers Not Supported in ApiGatewayFormatV2
Summary
Bref Multiple Value Headers Not Supported in ApiGatewayFormatV2
Original description
The description as published by the source.
Bref enable serverless PHP on AWS Lambda. When Bref is used in combination with an API Gateway with the v2 format, it does not handle multiple values headers. If PHP generates a response with two headers having the same key but different values only the latest one is kept. If an application relies on multiple headers with the same key being set for security reasons, then Bref would lower the application security. For example, if an application sets multiple Content-Security-Policy headers, then Bref would just reflect the latest one. This vulnerability is patched in 2.1.13.
