Prior to generator-jhipster 9.4.0 and react-jhipster 1.1.0, generated applications can persist attacker-controlled Blob data and companion ContentType values, return them through generated REST endpoints, and pass them to the generated openFile helper in generators/client/generators/common/templates/src/main/webapp/app/shared/jhipster/data-utils.ts.ejs. The helper uses the returned ContentType as the browser Blob MIME type and opens an object URL, so a normal authenticated user with write access to a Blob-bearing entity can store active HTML or SVG content that may execute under the application origin when a privileged user opens it. Exploitability depends on the generated application's content security policy and target-browser Blob behavior. This issue is fixed in generator-jhipster 9.4.0 and react-jhipster 1.1.0.","state":0,"publishedAt":"2026-10-08T18:17:19.277+00:00","modifiedAt":"2026-10-09T12:17:07.987+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N","score":7.6,"severity":"HIGH"}],"references":["https://github.com/jhipster/generator-jhipster/commit/efe95edd4dedc3379735094936439410a51ce3d9","https://github.com/jhipster/generator-jhipster/pull/34807","https://github.com/jhipster/generator-jhipster/releases/tag/v9.4.0","https://github.com/jhipster/generator-jhipster/security/advisories/GHSA-9ffp-22j7-56r2"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-107303","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-79"],"productCriteria":[],"sourceDates":{"published":"2026-10-08T18:17:19.277","lastModified":"2026-10-09T12:17:07.987"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
