AI-suggested
Until an official fix or update is available, administrators should review their User Profile Builder plugin configuration and avoid using the vulnerable non-default settings that enable this issue.
Description
The User Profile Builder WordPress plugin before 3.16.4 does not correctly bind the automatic login performed after user registration to the newly created account, allowing unauthenticated attackers to obtain an authenticated session for an arbitrary existing user, including administrators, on sites using a supported but non-default configuration.
