Upgrade express-hbs to version 2.4.0 or higher.
Overview
express-hbs is an Express handlebars template engine complete with multiple layouts, partials and blocks.
Affected versions of this package are vulnerable to Information Exposure. The layout parameter may trigger file disclosure vulnerabilities in downstream applications. This potential vulnerability is somewhat restricted in that only files with existing extensions (i.e. file.extension) can be included, files that lack an extension will have .hbs appended to them.
