CVE-2021-22142
Description
Kibana contains an embedded version of the Chromium browser that the Reporting feature uses. An attacker potentially is able to leverage known Chromium vulnerabilities to conduct further attacks.
Statement
The kibana reporting feature is part of the X-Pack features [1]. In OpenShift Container Platform (OCP) the kibana components have X-Pack security features disabled by default. The X-Pack plugin can be used only in the enterprise version [2] [3]. Hence the open source version is unaffected 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).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Access Control
Technical Impact: Gain Privileges or Assume Identity; Bypass Protection Mechanism; Read Application Data; Modify Application Data
An attacker can trick a user into performing actions that are masked and hidden from the user's view. The impact varies widely, depending on the functionality of the underlying application. For example, in a social media application, clickjacking could be used to trick the user into changing privacy settings.
