TL;DR

Affected versions of this package are vulnerable to Directory Traversal due to improper path sanitization in the getBlobByKey implementations. An attacker could exploit this vulnerability by crafting a request containing relative key (e.g., ../) to escape the intended serving directory. It could allow access to arbitrary files on the server's file system, potentially leading to the disclosure of sensitive information.
