Authorization Bypass Through User-Controlled Key

CVE-2026-23754

Severity High
Score 8.7/10

Summary

D-Link D-View 8 versions 2.0.1.107 and below contain an improper access control vulnerability in backend API endpoints. Any authenticated user can supply an arbitrary user_id value to retrieve sensitive credential data belonging to other users, including super administrators. The exposed credential material can be reused directly as a valid authentication secret, allowing full impersonation of the targeted account. This results in complete account takeover and full administrative control over the D-View system.
