OK then I propose the following impact description:
========
Title: Information leak and Denial of Service using XML entities
Reporter: Jonathan Murray (NCC Group)
Products: Keystone
Affects: All versions
Description:
Jonathan Murray from NCC Group reported a vulnerability in the parsing of XML requests in Keystone. By using entities in XML requests, an unauthenticated attacker may crash the Keystone API server, resulting in a denial of service. Authenticated attackers may also leverage XML entities to read the content of a local file on the Keystone API server. This only affects servers with XML support enabled (with keystone.
=========
Remaining tasks before disclosure:
