Description
The Forminator Forms plugin for WordPress is vulnerable to unauthorized modification of data via the AWeber integration in all versions up to, and including, 1.58.0 due to a missing authorization check when updating an existing subscriber and unrestricted tag removal. This makes it possible for unauthenticated attackers to submit a form with another person's e-mail address to overwrite that existing AWeber subscriber's fields and tags, including removing tags not managed by the form connection. Exploitation requires a form connected to the AWeber integration.
