This vulnerability can be exploited by attackers to cause service disruptions in applications utilizing the parser. Organizations using affected versions should prioritize upgrading to 3.3.0 or later to mitigate the risk of CPU exhaustion attacks.

Original NVD Description
Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.3.0, a run of closed tilde, equals-sign, or caret marker pairs around a character causes quadratic work in src/mistune/plugins/formatting.py when the strikethrough, mark, or insert plugin scans for matching markers from each possible start position, allowing denial of service through CPU exhaustion. This issue is fixed in version 3.3.0.
