Fluent Support <= 2.4.7 — Unauthenticated Limited Modification of Linked Customer Profile Fields via Fluent Forms Feed

The Fluent Support – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to unauthenticated modification of a linked customer's stored profile fields in versions up to, and including, 2.4.7 Its first-party Fluent Forms integration (FeedIntegration::notify()) opens a ticket from each public form submission and, for a logged-out submitter, resolves the submitted email to an existing WordPress account via get_user_by('email', ...) without verifying the submitter controls that address, then passes the attacker-supplied data to Customer::maybeCreateCustomer(). This makes it possible for unauthenticated attackers to overwrite a limited set of a registered customer's stored profile fields where an administrator has enabled a FluentSupport feed on a public form. The email address, role and status are never changed; first and last name are overwritten only when the target user has no name set in user meta; and other fields (title, address, city, state, zip, country) are writable only where an administrator has mapped them in the feed.

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Fluent Support 2.5.0 closes this, and updating the plugin is the step that ends it.
