Doc Text:
A flaw was found in Acer NitroSense software. An unauthenticated local attacker can connect to the Electron DevTools endpoint, exposed on localhost TCP port 9993. This allows the attacker to execute JavaScript in a privileged application context due to enabled Chromium remote debugging, leading to arbitrary code execution.

Description OSIDB Bzimport 2026-09-23 07:42:53 UTC
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.
