Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the getUploadLength() function. An attacker can repeatedly trigger post-upload hooks with arbitrary filenames and empty file contents by supplying a negative value in the Upload-Length header during a TUS upload. This can result in the execution of configured hooks, such as those for virus scanning or notifications, without actually uploading any data, potentially leading to resource exhaustion or abuse of business logic.
