CVE-2021-32822 (GCVE-0-2021-32822)

Vulnerability from cvelistv5 – Published: 2021-08-16 18:45 – Updated: 2024-08-03 23:33

Title

File disclosure in hbs

Summary

The npm hbs package is an Express view engine wrapper for Handlebars. Depending on usage, users of hbs may be vulnerable to a file disclosure vulnerability. There is currently no patch for this vulnerability. hbs mixes pure template data with engine configuration options through the Express render API. By overwriting internal configuration options a file disclosure vulnerability may be triggered in downstream applications. For an example PoC see the referenced GHSL-2021-020.
