glance node module before 3.0.4 suffers from a Path Traversal vulnerability due to lack of validation of path passed to it, which allows a malicious user to read content of any file with known path.
Versions of the package glance before 3.0.9 are vulnerable to Directory Traversal that allows users to read files outside the public root directory. This is related to but distinct from the vulnerability reported in [CVE-2018-3715](https://security.snyk.io/vuln/npm:glance:20180129).
