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 unbounded resource consumption during expression evaluation in the CalculateToString, CalculateLongWithInt, and CalculateBigIntegerNoFit functions. An attacker can exhaust system memory or CPU resources by supplying specially crafted templates that trigger excessive string multiplication, unbounded bit shifting, or large range enumerations in built-in functions. This can lead to process termination or significant performance degradation.
