CVE-2026-75908Newsletters <= 4.17 - Missing Authorization to Authenticated (Author+) Arbitrary Modification via 'newsletters_mailinglistsroles' POST Parameter

contrid Newsletters Publicada: (hace 2 meses)

Descripción

The Newsletters plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.17. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to send arbitrary newsletter emails to users of any WordPress role, including administrators, by forging POST fields during a normal post submission. This allows an attacker-supplied role slug via the newsletters_mailinglistsroles POST field to be passed directly to get_users(), enabling unauthorized mass-mailing and potential phishing against privileged site users through the site's own outbound email channel.
