CVE-2020-36669: JetBackup – WP Backup, Migrate & Restore <= 1.3.9 - Cross-Site Request Forgery to Arbitrary File Upload

The JetBackup – WP Backup, Migrate & Restore plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including 1.3.9. This is due to missing nonce validation on the backupguardgetimportbackup() function. This makes it possible for unauthenticated attackers to upload arbitrary files to the vulnerable site's server via a forged request, granted they can trick a site's administrator into performing an action such as clicking on a link.
