Administrator escalation via unrestricted user-meta updates
Published Sep 6, 2024 · Updated Apr 8, 2026
Privilege escalation in Tribulant Software Newsletters 4.9.9.2 and earlier allows remote authenticated users to become administrators. The screen-options handler writes attacker-selected user metadata without restricting which metadata keys can be changed. Exploitation requires an administrator to grant a lower-privileged account access to the plugin's Sent & Draft Emails page.
