CVSS Score
-The vulnerability stems from HttpClientBuilder's failure to enforce a non-null X509HostnameVerifier during SSL socket factory creation. The commit diff shows the fix adds a null-check and defaults to BROWSER_COMPATIBLE_HOSTNAME_VERIFIER, proving the original code allowed null values. This matches the CVE description about disabled hostname verification due to unvalidated null verifier.
