CVE-2022-0633Public exploitNetwork attack vector

Subscriber-level backup disclosure via heartbeat nonce leak

Published Feb 17, 2022 · Updated Aug 2, 2024

Incorrect authorization in UpdraftPlus Free before 1.22.3 and Premium before 2.22.3 allows remote authenticated users to download backups. UpdraftPlus_Admin::process_status_in_heartbeat returns active-job data, including a backup nonce, without confirming administrative capability; that nonce then satisfies the download check. Any WordPress account, including a Subscriber, can retrieve the latest site and database backup when an existing backup is present, exposing its non-public contents.
