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.
