CVE-2026-119213 (CVSS 3.7)

Description

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.
