CVE-2026-77752: Unknown Temporary Login Without Password

High severity, CVSS 7.2. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Unknown Temporary Login Without Password: from 1.5, before 1.9.9 (fixed in 1.9.9)
