Backup Migration <= 1.3.7 - Unauthenticated Remote Code Execution

Published Dec 15, 2023 · Updated Apr 8, 2026 · Assigned by Wordfence

Vendor: Inisev Product: BackupBliss – Backup & Migration with Free Cloud Storage Category: Web / CMS

Description

The Backup Migration plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.3.7 via the /includes/backup-heart.php file. This is due to an attacker being able to control the values passed to an include, and subsequently leverage that to achieve remote code execution. This makes it possible for unauthenticated attackers to easily execute code on the server.
