CVE-2026-50228

2th percentile - higher than 2% of all known CVEs

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.

A local attacker can gain full control over the application and execute arbitrary code in its context, potentially leading to system compromise or privilege escalation. However, this requires prior access to the machine.

Update Acer NitroSense to a version later than 5.2.63 that disables remote debugging in production. Restrict local access to port 9993 and consider blocking it with a firewall.
