Summary
Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.3.0, Include.parse() joins and normalizes user-supplied include paths without verifying that the result remains within the intended markdown directory, allowing crafted include paths to access files outside that directory when markdown files are processed using md.read().
This issue is fixed in version 3.3.0. This can lead to information disclosure when markdown files are processed.
This Moderate impact flaw in Mistune, a Python Markdown parser, allows for information disclosure. When processing specially crafted markdown files, an attacker can exploit improper path verification in the `Include.parse()` function to access files outside the intended markdown directory.
Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-22.
