UpdraftPlus WordPress Backup Plugin < 1.22.3 - Sensitive Information Disclosure

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

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.
