CVE-2026-49190Network attack vector

Authenticated command execution via unchecked opcode authorization

Published Jun 4, 2026 · Updated Jun 4, 2026

Command injection in Acer Connect M6E 5G Mobile WiFi firmware M6E_AI_1.00.000019 and earlier allows remote authenticated users to execute commands. The instruction-processing path accepts multiple internal opcodes without enforcing an authorization decision for each opcode. Low-privileged network access is sufficient, and successful exploitation can install unauthorized applications or execute commands on the router.
