Summary
Incorrect handling of CORS preflight request headers in hapi
Versions of hapi prior to 11.0.0 implement CORS incorrectly, allowing for configurations that at best return inconsistent headers, and at worst allow cross-origin activities that are expected to be forbidden.
If the connection has CORS enabled but one route has it off, and the route is not GET, the OPTIONS prefetch request will return the default CORS headers and then the actual request will go through and return no CORS headers. This defeats the purpose of turning CORS on the route.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
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. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2015-9236? CVE-2015-9236 is a medium-severity security vulnerability in hapi (npm), affecting versions < 11.0.0. It is fixed in 11.0.0.
- Which versions of hapi are affected by CVE-2015-9236? hapi (npm) versions < 11.0.0 is affected.
- Is there a fix for CVE-2015-9236? Yes. CVE-2015-9236 is fixed in 11.0.0. Upgrade to this version or later.
- Is CVE-2015-9236 exploitable, and should I be worried? Whether CVE-2015-9236 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.

- What actually determines whether CVE-2015-9236 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.
