CVE-2026-76864

Impact

NR255-V version 1.5.130703 fails to sanitize QoS rule names before they are parsed via eval() in qos_xianz_add_cgi, qos_xianz_show_cgi, qos_filter_add_cgi, and qos_filter_show_cgi handlers. An attacker can inject persistent script code through crafted QoS rule name input that executes when the stored data is later processed by the affected handlers.'
