Overview

Scriban is a

Scriban is a fast, powerful, safe and lightweight scripting language and engine for .NET, which was primarily developed for text templating with a compatibility mode for parsing liquid templates.

Today, not only Scriban can be used in text templating scenarios, but also can be integrated as a general scripting engine: For example, Scriban is at the core of the scripting engine for kalk, a command line calculator application for developers.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the array.insert_at() function. An attacker can cause the application to exhaust system memory and terminate unexpectedly by supplying a template with large index value (such as {{ [1] | array.insert_at 200000000 'x' | array.size }}), resulting in unbounded memory allocation.
