What is CVE-2026-22082?

A security issue has been identified in Tenda wireless routers, specifically in the 300Mbps Wireless Router F3 and N300 Easy Setup Router. This vulnerability arises from the use of login credentials as the session ID within the web-based administrative interface. A remote attacker can exploit this flaw by intercepting network traffic, allowing them to capture the session ID during its transmission if it occurs over an unsecured network.
