After verifying the fix commit (apache/tomcat@8a83c3c), the only modified file is java/org/apache/tomcat/util/net/AprEndpoint.java. This file is not included in the org.apache.tomcat:tomcat-util artifact, so that package is not affected by this vulnerability. I've updated the affected packages list accordingly.

Updated the GHSA advisory's "Affected packages" field to correctly identify the packages that are actually impacted by this vulnerability. The previous entry did not accurately reflect the real scope of the issue.
Threat Metrics should not be included in the CVSS vector string for vulnerabilities.
