Scriban before 7.2.0 Denial of Service via array.insert_at
Scriban before 7.2.0 contains a denial of service vulnerability in the array.insert_at function that allocates unbounded null entries without respecting LoopLimit or LimitToString constraints. Attackers can supply a large index parameter to trigger OutOfMemoryException and crash the host process in under a second.
