Technical details
The vulnerability is a privilege escalation (CWE-269) within the Android-based firmware of the Acer Connect M6E 5G router. A core Broadcast Receiver is exported with public access permissions but lacks proper validation of the calling component. A local attacker or a malicious application on the device can send intents to this receiver to trigger administrative operations without authorization. Acer recommends updating firmware to versions that set 'exported=false' or enforce signature-level permissions for this component.
