CVE-2019-12419
Description
A flaw was found in cxf in versions prior to 3.2.11 and 3.3.4. The access token services do not properly validate that an authenticated principal is equal to that of the supplied clientId parameter allowing a malicious client to use an authorization code that has been issued to a different client as their own. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Statement
In OpenShift Logging the openshift-logging/elasticsearch6-rhel8 container bundles the vulnerable version of apache-cxf, but the vulnerable class is not shipped, hence this component is not affected by this vulnerability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
CVSS v3 Score Breakdown

Red Hat CVSS v3 Score Explanation
Red Hat Products do not enable the many conditions required for this flaw, and as such have a base score that differs from NVD's base evaluation, AC:L -> AC:H. This changed the base flaw impact as well, but does not alter individual product impacts.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability,Access Control
Technical Impact: Read Application Data; Gain Privileges or Assume Identity; Execute Unauthorized Code or Commands
This weakness can lead to the exposure of resources or functionality to unintended actors, possibly providing attackers with sensitive information or even execute arbitrary code.
