Abstract

   When security vulnerabilities are discovered by independent security
   researchers, they often lack the channels to report them properly.
   As a result, security vulnerabilities may be left unreported.  This
   document defines a format ("security.txt") to help organizations
   describe the process for security researchers to follow in order to
   report security vulnerabilities.
