    Insecure template handling in Express-handlebars

    CVE-2021-32820 · GHSA-fr76-2wp8-fp92

    Affected
    • npm express-handlebars < 5.3.1
    Fixed in
    5.3.1· Vendor fix available
    Issue
    Express-handlebars is a Handlebars view engine for Express. Express-handlebars mixes pure template data with engine configuration options through the Express render API. More specifically, the layout parameter may trigger file disclosure vulnerabilities in downstream applications. This potential vulnerability is somewhat restricted in that only files with existing extentions (i.e. file.extension) can be included, files that lack an extension will have .handlebars appended to them. For complete details refer to the referenced GHSL-2021-018 report. Notes in documentation have been added to help users avoid this potential information exposure vulnerability. A fix is discussed in https://github.com/express-handlebars/express-handlebars/pull/163

    Recommended action: Upgrade to 5.3.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
