Details

As written in the advisory (Markdown source, shown as plain text).

Squirrelly is a template engine implemented in JavaScript that works out of the box with ExpressJS. Squirrelly mixes pure template data with engine configuration options through the Express render API. By overwriting internal configuration options remote code execution may be triggered in downstream applications. Version 9.0.0 has a fix for this issue. For complete details refer to the referenced [GHSL-2021-023](https://securitylab.github.com/advisories/GHSL-2021-023-squirrelly/).
