Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Scriban versions before 7.0.0, and the Scriban.Signed package before 7.0.0, can crash on deeply nested array initializers even with the expression depth limit added by an earlier fix. An attacker who can supply template text to Template.Parse can trigger a StackOverflowException, which terminates the whole process. Upgrade Scriban and Scriban.Signed to 7.0.0 or later. The source gives few details on other workarounds.
