Details

PyMdown Extensions is a set of extensions for the Python-Markdown markdown project. From 10.0.1 until 10.21.3, pymdownx.snippets uses a string-prefix containment check in SnippetPreprocessor.getsnippetpath() in pymdownx/snippets.py when restrict_base_path: True, allowing markdown snippet directives to read files from sibling paths that share the same basepath prefix, such as docs and docsinternal. This is a regression of CVE-2023-32309. This issue is fixed in version 10.21.3.
