CVE-2026-49196Network attack vector

Authenticated command execution via unsanitized MAC address

Published May 29, 2026 · Updated May 29, 2026

Command injection in Acer Predator Connect W6x firmware W6x_GBL_2.00.000005 and earlier allows remote authenticated users to execute shell commands. The Web Admin Panel's Wi-Fi device blocking feature passes an unsanitized MAC address field into system command execution. Administrator access to the router interface is required, after which injected commands can read or alter router data or interrupt service.
