Amazon Linux 2023 Security Advisory: ALAS2023-2026-1679
Advisory Released Date: 2026-05-14
Advisory Updated Date: 2026-05-14
Severity:
Important
Issue Overview:
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. (CVE-2026-41066)
Affected Packages:
python3.13-lxml
Issue Correction:
Run dnf update python3.13-lxml --releasever 2023.11.20260511 or dnf update --advisory ALAS2023-2026-1679 --releasever 2023.11.20260511 to update your system.
