CVE-2026-26462 describes a remote code execution vulnerability in Offline Hospital Management System 5.3.0 caused by an insecure Electron renderer configuration. Specifically, Node.js integration is enabled while context isolation is disabled, permitting JavaScript in the renderer process to invoke Node.js APIs and execute arbitrary OS commands. This configuration flaw exposes the application to potential remote compromise. No CVSS score or remediation details have been published yet.

An attacker who can execute JavaScript in the renderer process may gain the ability to run arbitrary operating system commands remotely. This could lead to full system compromise, data theft, or disruption of hospital management operations. However, no known exploits have been reported in the wild so far.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting access to the application and monitor for updates from the vendor. Avoid running untrusted code within the application environment.
