UpdraftPlus WordPress Backup Plugin < 1.22.3 - Sensitive Information Disclosure

Missing Authorization
CVE CVE-2022-0633
CVSS 6.5 (Medium)
Publicly Published February 17, 2022
Last Updated January 22, 2024
Researcher Marc-Alexandre Montpas


The UpdraftPlus WordPress plugin Free before 1.22.3 and Premium before 2.22.3 do not properly validate a user has the required privileges to access a backup's nonce identifier, which may allow any users with an account on the site (such as subscriber) to download the most recent site & database backup. The UpdraftPlus WordPress Backup Plugin plugin for WordPress is vulnerable to authorization bypass due to a missing capability check when performing a heartbeat function in versions up to 1.22.3. This makes it possible for authenticated attackers with minimal permissions such as a subscriber to retrieve the path to arbitrary back-up files which can subsequently be downloaded and used to gain sensitive information about the system. This also affects premium versions before before 2.22.3.

Wordfence blocked 612 attacks targeting this vulnerability in the past 24 hours.
