Severity

6.8 (Medium) CVSS_V3 - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N CVSS Calculator

Summary

Remote code execution via the `pretty` option.

Details

Impact

If a remote attacker was able to control the pretty option of the pug compiler, e.g. if you spread a user provided object such as the query parameters of a request into the pug template inputs, it was possible for them to achieve remote code execution on the node.js backend.

Patches

Upgrade to pug@3.0.1 or pug-code-gen@3.0.2 or pug-code-gen@2.0.3, which correctly sanitise the parameter.

Workarounds

If there is no way for un-trusted input to be passed to pug as the pretty option, e.g. if you compile templates in advance before applying user input to them, you do not need to upgrade.
