CVE-2026-26462

Vulnerability

Offline Hospital Management System version 5.3.0 [1] is vulnerable to remote code execution due to an insecure Electron renderer configuration. The application enables Node.js integration while disabling context isolation, which allows JavaScript code executed in the renderer process to directly access Node.js APIs and execute arbitrary operating system commands. This misconfiguration violates Electron security best practices and exposes the system to full compromise.

Exploitation

An attacker needs to deliver malicious JavaScript to the renderer process, for example by convincing a user to open a crafted HTML page or by injecting script into a page loaded by the application. Once the JavaScript runs in the renderer, it can use Node.js APIs such as child_process to execute arbitrary commands on the user's system with the privileges of the application.

Impact

Successful exploitation allows the attacker to execute arbitrary operating system commands, leading to full remote code execution. The attacker can essentially take over the user's system, reading, modifying, or deleting files, installing malware, and accessing sensitive data processed by the application.

Mitigation

As of the publication date (2026-05-18), no fixed version has been released by the vendor [1]. Users should disable Node.js integration and enable context isolation in Electron settings, or migrate to an alternative solution that follows secure Electron configuration best practices. The vulnerability is not currently listed in CISA's Known Exploited Vulnerabilities (KEV) catalog.
