Technical Analysis
CVE-2026-111982 is an improper privilege management vulnerability (CWE-269) in the User Profile Builder WordPress plugin prior to version 4.0.5. The plugin fails to verify that a user is authorized to edit the specific account selected on its front-end Edit Profile form. This allows a Multisite subsite Administrator to modify any other user's email address, including that of a Network Super Admin. By changing the email, the attacker can initiate a password reset and gain control over the targeted account.
Potential Impact
An attacker with Administrator privileges on a Multisite subsite can escalate their privileges by taking over any user account, including the Network Super Admin, through unauthorized email changes and subsequent password resets. This compromises the integrity and control of the entire WordPress Multisite network.
