CVE-2026-9254
An unauthenticated OS command injection vulnerability exists in the parental control functionality of Archer BE800 V1, BE3600 V1, and AX75 V1 due to improper filtering and neutralization of special characters in certain parameters. A LAN-based attacker can inject arbitrary commands and execute them with root privileges.
Successful exploitation may result in complete device compromise and impact the confidentiality, integrity, and availability of the affected device and network traffic.
