CVE-2026-111982 · Severity: info · Published 2026-10-23

Profile Builder is a WordPress plugin that manages user profiles and registration. A vulnerability in versions before 4.0.5 allows a site administrator in a WordPress Multisite subsite to change any other user's email address without authorization, including that of a network super administrator. An attacker can then use the password-reset flow to take over the compromised account.

## How to fix

- Fixed in 4.0.5

## Technical details

The plugin fails to verify user authorization when processing Edit Profile form submissions on the front-end, allowing privilege escalation via unauthorized email modification. An authenticated site admin in a Multisite subsite can exploit this to change any user's email—including network-level administrators—and gain full account control. The vulnerability requires existing admin access within the subsite and affects only Multisite WordPress deployments.
