CVE-2026-58457 is a critical-severity flaw (CVSS 9.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02) contains an unauthenticated OS command injection vulnerability that allows network-adjacent attackers to execute arbitrary shell commands by injecting unsanitized input through the smacfilter_conf handler in the commuos web backend. Attackers can append semicolon-delimited payloads to the name, enable, or mac GET parameters, which are passed without sanitization into sprintf() to build uci
