Does this matter?
Lower severity and a low EPSS score (1.60%). Track it; it rarely justifies an emergency change on its own.

There is a stack exhaustion problem caused by the mark_beginning_as_normal function making recursive calls to itself in certain scenarios involving lots of '*' characters. Remote attackers could leverage this vulnerability to cause a denial-of-service.
