Description

The nestjs-proxy library did not have a way to block sensitive cookies (e.g. session cookies) from being forwarded to backend services configured by the application developer. This could have led to sensitive cookies being inadvertently exposed to such services that should not see them.

The patched version now blocks cookies from being forwarded by default. However developers can configure an allow-list of cookie names by using the allowedCookies config setting. Further details of this feature can be found in the library's README on Github or NPM.
