1. What is CVE-2014-3662? CVE-2014-3662 is a medium-severity security vulnerability in org.jenkins-ci.main:jenkins-core (maven), affecting versions >= 1.566, < 1.583. It is fixed in 1.583, 1.565.3.
2. Which versions of org.jenkins-ci.main:jenkins-core are affected by CVE-2014-3662? org.jenkins-ci.main:jenkins-core (maven) versions >= 1.566, < 1.583 is affected.
3. Is there a fix for CVE-2014-3662? Yes. CVE-2014-3662 is fixed in 1.583, 1.565.3. Upgrade to this version or later.
4. Is CVE-2014-3662 exploitable, and should I be worried? Whether CVE-2014-3662 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

5. What actually determines whether CVE-2014-3662 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
6. How do I fix CVE-2014-3662?
   • Upgrade org.jenkins-ci.main:jenkins-core to 1.583 or later
   • Upgrade org.jenkins-ci.main:jenkins-core to 1.565.3 or later
