CVE-2026-6373

Unauthenticated information disclosure via web fingerprinting

Published Aug 10, 2026 · Updated Aug 10, 2026

Information exposure in Zyxel Networks WAH7601 through 20072026 allows remote attackers to fingerprint its web interface. The CNA identifies web application fingerprinting but does not disclose the exposed endpoint, response fields, or operation that releases them. Exploitation requires adjacent-network access, and the documented consequence is information disclosure without modification or interruption.
