Summary
Duplicate Advisory: Mistune: Path Traversal and XSS in Include directive
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-h7ww-273w-6cm8. This link is maintained to preserve external references.

Original Description

Mistune before 3.3.0 contains a path traversal vulnerability in the Include directive that allows attackers to read arbitrary files by supplying ../ sequences in include paths. Attackers can also inject HTML through unescaped error messages and included file contents to perform cross-site scripting even when escape=True is set.
