What it is

Scriban before 7.0.0 contains an uncontrolled recursion vulnerability in the object.to_json builtin function that lacks depth limits and circular reference detection. Attackers can craft templates with self-referencing objects to trigger unbounded recursion, causing a StackOverflowException that fatally terminates the hosting .NET process.
