What happened

ZTNET is a ZeroTier web UI for private controllers with multiuser and organization support. Prior to 0.8.0, any authenticated low-privilege user can permanently deactivate another account, including an administrator, through POST /api/auth/user/invalidateUser. In src/pages/api/auth/user/invalidateUser.ts, getServerSession checks only that a session exists and does not compare session.user.

id with the client-supplied userId. Supplying a victim's userId and a deviceId for which no matching pair exists in UserDevice makes the handler set the target account's isActive to false. Login is then refused by src/server/auth.ts with account-expired.

An attacker needs only a normal authenticated account and the victim's user ID, which may be obtainable from member lists, UI responses, logs, or other application metadata. This can lock administrators out, disrupt organization management, and deny access to any targeted user. This issue is fixed in version 0.8.0.

About this data

This record was ingested from a data source. Retrieved: Oct 30, 2026, 22:30 UTC. Ingestion is not an independent editorial investigation.

NVD status: Received. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
