    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 `[email protected]` or `[email protected]` or `[email protected]`, 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. ### References Original report: https://github.com/pugjs/pug/issues/3312 ### For more information If you believe you have found other vulnerabilities, please **DO NOT** open an issue. Instead, you can follow the instructions in our [Security Policy](https://github.com/pugjs/pug/blob/master/SECURITY.md)
