Title
admin3 through 3.0.0 Arbitrary File Write via Path Traversal in Storage Upload Filename
Summary
admin3 through 3.0.0 fails to sanitize client-supplied filenames in the upload handler, allowing authenticated users to write files outside the storage root on Windows deployments. Attackers can use dot-dot path segments in filenames to escape the configured storage directory and overwrite arbitrary files accessible to the server process.
