CVE-2026-119213
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.

CVE-2026-71863
SecureDrop is an open-source whistleblower submission system that media organizations can use to securely accept documents from, and communicate with anonymous sources. From 2.13.0 until 2.16.1, running the securedrop-admin install Ansible playbook with journalist alerts disabled leaves the journalist alert key filename empty, causing the copy task to transfer every file in ~/.config/securedrop-admin/, including Onion Service client authentication credentials, to the Monitor Server. An attacker must first compromise the privileged Monitor Server to obtain the credentials, and the credentials remain an additional protection layer rather than sufficient access by themselves because the Journalist Interface still requires a username, passphrase, and MFA, while SSH access still requires SSH keys. This issue is fixed in version 2.16.1.
