Summary
Fix high severity security issue in
packages/markitdown/src/markitdown/converters/_markdownify.py.Vulnerability
V-001packages/markitdown/src/markitdown/converters/_markdownify.py:112Description: The markitdown converter processes RSS/XML documents at the convert_input entry point without disabling XML external entity (XXE) resolution. Python's standard xml.etree.ElementTree and lxml parsers, when used with default settings, may resolve external entity declarations embedded in XML documents. An attacker can craft a malicious RSS/XML document containing an XXE declaration that instructs the parser to read a local file (e.g., /etc/passwd, application secrets, private keys) and embed its contents in the parsed output. Additionally, recursive entity expansion (Billion Laughs attack) can exhaust server memory and CPU, causing a denial of service.
