Description
CVE-2026-62967 is a missing authorization vulnerability in sinamics ztnet versions prior to 0.8.0. It allows any authenticated low-privilege user to deactivate another user's account, including administrators, by exploiting an API endpoint that does not properly verify user permissions. This can result in denial of access and disruption of organization management. The issue is fixed in version 0.8.0.
