Profile Builder < 4.0.1 - Admin+ PHP Object Injection via Import/Export

Published Aug 29, 2026 CVSS 3.1 · 6.6 Medium EPSS < 1% KEV · Not listed
Description
The User Profile Builder WordPress plugin before 4.0.1 does not validate the type of data being deserialized when importing a configuration file, allowing high privilege users such as administrators to conduct PHP Object Injection. The affected feature is a free add-on which is disabled by default, and no POP chain is present in the User Profile Builder WordPress plugin before 4.0.1 itself, so further impact requires a suitable gadget from another installed User Profile Builder WordPress plugin before 4.0.1 or .
