How to Fix CVE-2015-9243

To remediate this vulnerability, upgrade all affected Hapi dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

hapi fixed: 11.1.4 
npm install hapi@11.1.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls hapi

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2015-9243, inspect your project dependencies using npm:

npm ls hapi

Analyze the terminal output to locate any version of Hapi in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 11.1.4), your application is affected.

Note: The npm ls hapi command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Hapi, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of `hapi` prior to 11.1.4 are affected by a vulnerability that causes route-level CORS configuration to override connection-level or server-level CORS defaults. This may result in a situation where CORS permissions are less restrictive than intended. ## Recommendation Update hapi to version 11.1.4 or later.
