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).

The nlpweb/glance repository through 2014-06-27 on GitHub allows absolute path traversal because the Flask send_file function is used unsafely.

There is a Stored XSS vulnerability in the glance node module versions <= 3.0.5. File name, which contains malicious HTML (eg. embedded iframe element or javascript: pseudo-protocol handler in <a> element) allows to execute JavaScript code against any user who opens a directory listing containing such crafted file name.

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.
