GHSA-79p8-4cwq-rhqh Directory Traversal in jn_jj_server

• npm jn_jj_server: <= 0.0.8 (no fix yet)

Affected versions of `jn_jj_server` 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: ```http GET /../../../../../../../../../../etc/passwd HTTP/1.1 host:foo ``` Recommendation No patch is available for this vulnerability. It is recommended that the package is only used for local development, and if the functionality is needed for production, a different package is used instead.
