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).

Red Hat CVSS v3 Score Explanation
A successful attack using this vulnerability requires an existing session auth to be used in place of an access token validation. This translates to Password Required: Low, and not None. Also the affected Confidentiality, Integrity, and Availability are all impacted at a single instance of the multitenant system, and thus as Low impact.
