Affected versions of `cypserver` 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.
