CVE-2026-50209

Administrative takeover via unprotected registration broadcasts

Published Jun 4, 2026 · Updated Jun 4, 2026

Incorrect permission assignment in Acer Connect M6E firmware through M6E_AI_1.00.000019 allows local users to seize MDM control. The MDM registration broadcast receiver accepts events from untrusted local software and writes an attacker-supplied server address as the default management endpoint. Low-privileged code on the router is required; successful exploitation redirects administrative ownership and grants the external MDM server control of the device.
