Name of the Vulnerable Software and Affected Versions Wildog/flask-file-server versions through 2020-02-20

Description The issue allows absolute path traversal due to the unsafe use of the Flask send file function. This enables potential access to files outside the intended directory.

Recommendations For versions through 2020-02-20, consider restricting access to the send file function until a safer implementation is available. As a temporary workaround, review and limit file access permissions to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
