Vulnerability from github – Published: 2021-09-02 17:16 – Updated: 2021-08-26 17:12

Summary

Insertion of Sensitive Information into Externally-Accessible File or Directory and Exposure of Sensitive Information to an Unauthorized Actor in hbs

Details

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.
