Kerentanan Inefficient Algorithmic Complexity pada mistune project mistune. Skor CVSS 3.1 7.5 (High) menurut github.com.

Deskripsi (NVD)

Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.3.0, long sequences of well-formed double-asterisk or triple-asterisk emphasis pairs around a character cause quadratic work in src/mistune/inline_parser.py because the parser scans forward for matching close markers from every potential opening run, allowing denial of service in default Mistune parsing. This issue is fixed in version 3.3.0.
