WordPress · Backup Migration · CVE-2023-6972
**Name of the Vulnerable Software and Affected Versions**
Backup Migration plugin for WordPress versions up to, and including, 1.3.9
**Description**
The issue allows unauthenticated attackers to perform Path Traversal via the `content-backups` and `content-name`, `content-manifest`, or `content-bmitmp` and `content-identy` HTTP headers. This enables the deletion of arbitrary files, including the wp-config.php file, potentially leading to site takeover and remote code execution.
**Recommendations**
For versions up to, and including, 1.3.9, update to a version later than 1.3.9 to resolve the issue.
As a temporary workaround, consider restricting access to the `content-backups`, `content-name`, `content-manifest`, `content-bmitmp`, and `content-identy` HTTP headers until a patch is available.
Avoid using the affected HTTP headers in the Backup Migration plugin until the issue is resolved.
