CVE-2026-86150Network attack vector

Limited data disclosure via hard-coded WPA passphrase

Published Sep 5, 2026 · Updated Sep 8, 2026

Hard-coded credentials in Tenda CP3 27.5.57.101 allow remote authenticated users to read limited data through the hostapd service. An undisclosed function in custom-x/softap/hostapd mishandles the wpa_passphrase argument and applies hard-coded credentials. Exploitation requires high privileges and no user interaction; published scoring limits the consequence to confidentiality loss.
