The vulnerability in the getFullPath method allows an attacker to perform path traversal attacks. By manipulating the file paths, an attacker can save files, read files, and delete files outside the intended directory. This can lead to unauthorized access to sensitive information, data corruption, and potential denial of service by deleting critical files.

An attacker could exploit this vulnerability by providing a specially crafted file path to the mset, mget, or mdelete methods. For example, by using ../../../../ in the file path, the attacker can navigate to any directory on the filesystem. This allows the attacker to save malicious files, read sensitive information, or delete important files.

Users of version 0.2.5 of the software who utilize the getFullPath method for file operations are affected. This includes any applications or services that rely on this method for saving, reading, or deleting files.
