Background
The earlybird package is an npm module used for local development. It provides functionality for resolving relative file paths. However, it is vulnerable to a directory traversal attack, which allows a malicious actor to access files outside of the intended directory root. This can lead to the disclosure of private files on the vulnerable system.
Vulnerability Detail
The vulnerability in earlybird arises from its improper resolution of relative file paths. By exploiting this vulnerability, an attacker can craft a request that includes additional directory traversal sequences (../) to access files outside of the intended directory. For example, an attacker could send a GET request to access the /etc/passwd file on the system. This can result in the exposure of sensitive information.
How To Fix
No fixed version is published for this vulnerability.

As there is no patch available, a workaround for this vulnerability is to avoid using the earlybird package in production environments. Instead, consider using a different package that provides similar functionality but does not suffer from the directory traversal vulnerability.
Conclusion
The earlybird package is vulnerable to a directory traversal attack, which can lead to the disclosure of private files on the system. It is recommended to avoid using this package in production environments and switch to a different package that does not have this vulnerability.
