Scriban: array.insert_at index parameter DoS bypasses LoopLimit and LimitToString

Summary ArrayFunctions.InsertAt in Scriban allocates index - list.Count null entries in a tight C for loop with no bound on index. The function is exposed to template authors as array.insertat, and the fill loop ignores every existing safety control: LoopLimit, LimitToString, ObjectRecursionLimit...

Scriban: Built-in operations bypass LoopLimit and delay cancellation, enabling Denial of Service

Summary Scriban's LoopLimit only applies to script loop statements, not to expensive iteration performed inside operators and builtins. An attacker can submit a single expression such as 1..1000000 | array.size and force large amounts of CPU work even when LoopLimit is set to a very small value...
