Summary
High severity vulnerability that affects generator-jhipster
Generated code uses repository configuration that downloads over HTTP instead of HTTPS
Workarounds
Replace all custom repository definitions in build.gradle or pom.xml with their https version.
e.g.
<repository>
<id>oss.sonatype.org-snapshot</id>
<url>https://oss.sonatype.org/content/repositories/snapshots</url> // <-- must be httpS
<releases>
<enabled>false</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
maven { url "https://repo.spring.io/plugins-release" } // <-- must be httpS

Impact
Gradle users were using the http://repo.spring.io/plugins-release repositories in plain HTTP, and not HTTPS, so a man-in-the-middle attack was possible at build time.
GHSA-MC84-XR9P-938R has a CVSS score of 8.1 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (6.3.1); upgrading removes the vulnerable code path.

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.

Maven users should at least upgrade to 6.3.0 while Gradle users should update to 6.3.1.
If you are not able to upgrade make sure not to use a Maven repository via http in your build file.
Frequently Asked Questions
- What is GHSA-MC84-XR9P-938R? GHSA-MC84-XR9P-938R is a high-severity security vulnerability in generator-jhipster (npm), affecting versions < 6.3.1. It is fixed in 6.3.1.
- How severe is GHSA-MC84-XR9P-938R? GHSA-MC84-XR9P-938R has a CVSS score of 8.1 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of generator-jhipster are affected by GHSA-MC84-XR9P-938R? generator-jhipster (npm) versions < 6.3.1 is affected.
- Is there a fix for GHSA-MC84-XR9P-938R? Yes. GHSA-MC84-XR9P-938R is fixed in 6.3.1. Upgrade to this version or later.
- Is GHSA-MC84-XR9P-938R exploitable, and should I be worried? Whether GHSA-MC84-XR9P-938R 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 GHSA-MC84-XR9P-938R 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.
- How do I fix GHSA-MC84-XR9P-938R? Upgrade
