CyberRota Analysis
AI-GeneratedVersions 3.3.0 to 3.3.2 of the Mistune Python Markdown parser are vulnerable to a denial-of-service (DoS) attack due to excessive recursion triggered by deeply nested emphasis tokens in Markdown input. This flaw can lead to a RecursionError, causing the parsing process to crash when handling specially crafted Markdown content. Developers and organizations utilizing these versions should prioritize upgrading to version 3.3.3 to mitigate potential service disruptions.

Original NVD Description
Mistune is a Python Markdown parser with renderers and plugins. Versions 3.3.0 through 3.3.2 are vulnerable to DoS through deeply nested tokens. HTML rendering creates deeply nested emphasis tokens from consecutive asterisk characters, and recursive rendering in HTMLRenderer.render_token() can exceed Python's recursion limit and raise RecursionError, allowing crafted Markdown to crash a parsing process. This issue is fixed in version 3.3.3
