CVE-2026-26462 affects Offline Hospital Management System 5.3.0 and arises from an insecure Electron renderer configuration. Specifically, Node.js integration is enabled while context isolation is disabled, violating Electron security best practices. This misconfiguration permits JavaScript code executed in the renderer process to leverage Node.js APIs, enabling arbitrary command execution on the host operating system remotely. The vulnerability is classified under CWE-917 (Improper Neutralization of Input During Web Page Generation). The CVSS v3.1 base score is 7.3 (High), with network attack vector, low attack complexity, no privileges or user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation allows remote attackers to execute arbitrary operating system commands on affected systems running Offline Hospital Management System 5.3.0. This can lead to unauthorized system control, data compromise, and disruption of hospital management operations. The vulnerability impacts confidentiality, integrity, and availability of the system.

No official patch or remediation guidance is currently available from the vendor. Patch status is not yet confirmed—check the vendor advisory for current remediation guidance. As a best practice, users should avoid exposing the vulnerable application to untrusted networks and monitor for updates from the vendor. Remediation would typically involve disabling Node.js integration or enabling context isolation in the Electron configuration to prevent arbitrary code execution.
