CVE-2026-49188

Unauthenticated root command execution via ai_cmd sockets

Published Jun 4, 2026 · Updated Jun 4, 2026

Command injection in Acer Connect M6E firmware M6E_AI_1.00.000019 and earlier allows remote attackers to execute root commands via sockets. The root-privileged ai_cmd utility passes untrusted socket input directly to popen(), causing the shell to interpret attacker-supplied text as commands. No authentication or user interaction is required, but the attacker must reach the ai_cmd communication socket from an adjacent network.
