CVE-2026-19927Public exploitNetwork attack vector

Authenticated SSRF via unvalidated upload URL

Published Aug 16, 2026 · Updated Aug 16, 2026

Server-side request forgery in OpenBoxes before 0.9.8 allows remote authenticated users to read server-fetched content via url input. ProductController.upload() passed params.url directly to new URL(params.url).openStream(), saved the response into a Document object, and exposed that stored content back through the product document UI. Any authenticated Browser-level account could trigger the request, enabling readable access to internal web services or cloud metadata endpoints instead of a blind network probe.
