CVE-2026-50228
Electron DevTools Arbitrary Code Execution Vulnerability in NitroSense
Description
An unauthenticated local attacker can connect to the Electron DevTools endpoint exposed by Acer NitroSense software (versions up to and including 5.2.63) on localhost TCP port 9993. Because Chromium remote debugging is enabled in the production application, the attacker can execute JavaScript in the privileged application context and achieve arbitrary code execution.
