CVE-2026-19504Hinoki check available

Sensitive data disclosure via unvalidated resource URIs

Published Sep 15, 2026 · Updated Sep 15, 2026

Server-side request forgery in Fabric.js 7.2.0 allows remote attackers to disclose sensitive data via crafted canvas JSON. The loadFromJSON method passes image and other nested resource URIs to the loader without validation, causing the host to request attacker-selected network resources. The host application must process untrusted JSON in a server-side context; reachable data and request behavior depend on that application's network access.
