CRITICAL 9.8CVE-2023-6553 · Published 15/12/2023 · updated 17/06/2026

Package	Affected versions	Patched versions
backup migration backupbliss	`≤ 1.3.7`	No fix yet

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.
