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.

Release Notes

### [`v3.0.1`](https://togithub.com/pugjs/pug/releases/pug@3.0.1)
[Compare Source](https://togithub.com/pugjs/pug/compare/pug@3.0.0...pug@3.0.1)
#### Bug Fixes
- Sanitise the `pretty` option ([#3314](https://togithub.com/pugjs/pug/issues/3314))
If a malicious attacker could control the `pretty` option, it was possible for them to achieve remote code execution on the server rendering the template. All pug users should upgrade as soon as possible, see [#3312](https://togithub.com/pugjs/pug/issues/3312) for more details.
