HIGH7.5EPSS 0.04%lxml: Default configuration of iterparse() and ETCompatXMLParser() allows XXE to local files
發布日:2026/4/21修改日:2026/4/28
也稱為:DEBIAN-CVE-2026-41066
描述
lxml is a library for processing XML and HTML in the Python language. Prior to 6.1.0, using either of the two parsers in the default configuration (with resolve_entities=True) allows untrusted XML input to read local files. Setting the resolve_entities option explicitly to resolve_entities='internal' or resolve_entities=False disables the local file access. This vulnerability is fixed in 6.1.0.
