FKIE_CVE-2026-107303

Vulnerability from fkie_nvd - Published: 2026-10-08 18:17 - Updated: 2026-10-08 21:03
Severity
7.6 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N
Summary
JHipster is a development platform to quickly generate, develop, and deploy modern web applications and microservice architectures. 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.
