Temporary Login Without Password lets site admins take over multisite
Temporary Login Without Password from 1.5 through versions before 1.9.9 fails to require network-super-admin authority before granting those rights to a temporary or existing account. A single-site administrator on WordPress multisite can promote their own account or another account and take over the network. The authoritative export does not name the handler or privilege field.

This CVE was published Sep 12, 2026 and is one of 3 known issues for this plugin.
Update, patch or deactivate.
Update Temporary Login Without Password to 1.9.9 or later. The authoritative affected range ends before 1.9.9. The application-level fix must require current_user_can('manage_network') or the equivalent network-only capability and refuse caller-controlled super-admin promotion.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The Temporary Login Without Password WordPress plugin before 1.9.9 does not verify that the user requesting a temporary login holds network super admin rights before granting the new account those rights, allowing an administrator of a single site on a multisite network to take over the whole network. The same missing check also allows an existing account, including the attacker's own, to be promoted.
