CVE-2026-34474 is a vulnerability in ZTE ZXHN H298A 1.1 and H108N 2.6 routers that allows sensitive data exposure. A crafted request to the router's web interface can leak administrator passwords and WLAN pre-shared keys (PSKs), potentially enabling unauthorized access. Some firmware versions may only expose partial device identifiers such as serial numbers, ESSIDs, or MAC addresses.
