Mistune's formatting plugins for strikethrough, mark, and insert exhibit an algorithmic complexity vulnerability causing quadratic-time parsing on inputs with repeated marker pairs like `~~x~~`. This leads to excessive CPU usage when processing long runs of these markers, resulting in denial of service. The issue affects mistune versions from 1.2.0 up to but not including 4.6.1. A fix is available in version 4.6.1.
