Missing Authorization
CVE CVE-2022-4931
CVSS 4.3 (Medium)
Publicly Published February 23, 2022
Last Updated March 7, 2023
Researcher Ramuel Gall


The BackupWordPress plugin for WordPress is vulnerable to information disclosure in versions up to, and including 3.12. This is due to missing authorization on the heartbeat_received() function that triggers on WordPress heartbeat. This makes it possible for authenticated attackers, with subscriber-level permissions and above to retrieve back-up paths that can subsequently be used to download the back-up.

Wordfence blocked 135 attacks targeting this vulnerability in the past 24 hours.
