Directory Traversal in cyber-js

Affected versions of cyber-js resolve relative file paths, resulting in a directory traversal vulnerability. A malicious actor can use this vulnerability to access files outside of the intended directory root, which may result in the disclosure of private files on the vulnerable system.

Example request:

GET /../../../../../../../../../../etc/passwd HTTP/1.1
host:foo
