Security issues are treated very seriously and will, by default, takes precedence over other considerations including usability, performance, etc... Best effort will be used to mitigate side effects of a security change, but DSC must be secure by default.

If you believe that there is a security vulnerability in DSC, it must be reported using https://aka.ms/secure-at to allow for Coordinated Vulnerability Disclosure. Only file an issue, if MSRC has confirmed filing an issue is appropriate.
