Description
WordPress Plugin Backup, Restore and Migrate WordPress Sites With the XCloner is prone to a directory traversal vulnerability because it fails to sufficiently verify user-supplied input. Exploiting this issue can allow an attacker to obtain sensitive information (filenames of previous backups) that could aid in further attacks. WordPress Plugin Backup, Restore and Migrate WordPress Sites With the XCloner version 3.1.4 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 3.1.5 or latest
