Statmatic is a Laravel and Git powered content management system (CMS). Prior to version 5.17.0, assets uploaded with appropriately crafted filenames may result in them being placed in a location different than what was configured. The issue affects front-end forms with `assets` fields and other places where assets can be uploaded, although users would need upload permissions anyway. Files can be uploaded so they would be located on the server in a different location, and potentially override existing files. Traversal outside an asset container is not possible. This path traversal vulnerability has been fixed in 5.17.0.
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.
