  "title": "Stored cross-site scripting in JHipster-generated Blob handling",
  "summary": "Applications generated with affected JHipster packages can retain untrusted Blob content types and later open the associated file in the application origin. An authenticated user with write access to a Blob-bearing entity may target a more privileged user who opens that file; impact depends on the deployment's CSP and browser behavior.",
  "mitigation": "Upgrade generator-jhipster to 9.4.0 or later and react-jhipster to 1.1.0 or later, then regenerate or update affected generated code. Until updated, restrict writes to Blob-bearing entities and allow only validated, non-active file types.",
