CVE-2026-49008Network attack vector

Integrity compromise via hard-coded firmware keys

Published Aug 7, 2026 · Updated Aug 7, 2026

Hard-coded cryptographic keys in ZTE ZXHN F689 firmware allow remote authenticated users to obtain integrity-check credentials. The firmware leaves those credentials as unencrypted constants recoverable from its image, but ZTE has not identified the affected application function or retrieval path. Low-privilege network access is required, and the credentials allow integrity compromise of that function without reported service interruption.
