Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in iThemes BackupBuddy allows Path Traversal.This issue affects BackupBuddy: from 8.5.8.0 through 8.7.4.1.
Solution:
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
