Insecure Transmission Vulnerability in Tenda Wireless Routers_CVE-2026-22080

{
    "lastseen": "",
    "description": "This vulnerability exists in Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) due to the transmission of credentials encoded using reversible Base64 encoding through the web-based administrative interface. An attacker on the same network could exploit this vulnerability by intercepting network traffic and capturing the Base64-encoded credentials.\n\nSuccessful exploitation of this vulnerability could allow the attacker to obtain sensitive information and gain unauthorized access to the targeted device.",
