ASF Security (security@apache.org CNA) via NVD
The Apache Software Foundation is its own CVE Numbering Authority: every Apache project CVE (HTTP Server, Tomcat, ActiveMQ, Struts, Kafka, Airflow, OFBiz, Solr and 300+ more) is published by security@apache.org and announced on the projects' mailing lists. VulniPulse ingests the CNA feed from NVD filtered to security@apache.org — official, machine-readable, with affected/fixed versions embedded in each description. Per-project security pages (httpd.apache.org/security, tomcat.apache.org/security-XX.html) carry the vendor detail.
