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
Differences in the impact to Confidentiality, Integrity and Availability between Red Hat score and NVD one are due to the fact that HTTP request smuggling vulnerabilities are context dependent and their impact can greatly vary based on the specific infrastructure, application and configurations. Difference in the Scope metric is because the vulnerable component is httpd while the impacted component is any application who is attacked as a result of the HTTP request smuggling.
