Security Doesn’t Start With CVE Disclosure

Security doesn’t begin when a CVE is published. In the Tomcat CVE-2025-24813 case, the fix shipped quietly weeks before disclosure, meaning teams that routinely applied maintenance updates were already safe—while others were exposed despite fast reactions later. CVE scores, scanners, and compliance deadlines are lagging indicators, especially when components are embedded, forked, or end-of-life. Real security outcomes are determined by lifecycle governance, upgrade habits, and clear ownership—not by how quickly teams respond once a vulnerability is named.
