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.

Red Hat CVSS v3 Score Explanation

Red Hat's Justification for CVSS Difference

*PR : In order to access the affected functionality i.e. NumberFilter, the User must have valid Ansible Automation Hub credential. It doesn't have to be high privilege though. Hence, it feels adequate that Privilege Required should be Low i.e PR = L.
