Generated code uses repository configuration that downloads over HTTP instead of 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. Patches 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. Workarounds Replace all custom repository definitions in build.gradle or pom.xml with their https version. e.g. References https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H https://max.computer/blog/how-to-take-over-the-computer-of-any-java-or-clojure-or-scala-developer/ For more information If you have any questions or comments about this advisory: Open an issue in https://github.com/jhipster/generator-jhipster/issues

# Patch Next advisory brief: GHSA-mc84-xr9p-938r

Advisory: High severity vulnerability that affects generator-jhipster
IDs: GHSA-mc84-xr9p-938r
Record: https://patchnext.com/advisories/ghsa-mc84-xr9p-938r (revision 2, source checked 26 Oct 2026, 12:07 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: generator-jhipster 6.3.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm generator-jhipster: affected < 6.3.1; fixed in 6.3.1

## Suggested inspection (read-only)
- `npm ls generator-jhipster --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on generator-jhipster.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
