Scriban versions from 3.0.0 through 7.2.5 contain a denial of service vulnerability in the ScriptRange.Multiply operator that bypasses LoopLimit when the left operand is a lazy sequence. Attackers can supply templates with array multiplication on lazy sequences to execute billions of uncharged iterations, pinning CPU cores and exhausting garbage collection resources even when LoopLimit is set to 1.
