Summary

Scriban versions 3.0.0 through 7.2.0 contain a denial of service vulnerability in the array multiplication operator that allocates memory without enforcing LoopLimit or overflow-safe arithmetic checks. Attackers can supply a large integer multiplier in a template to force multi-gigabyte memory allocations, causing resource exhaustion and availability degradation.
