An update for python-markdown is now available for openEuler-24.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-1787 Final 1.0 1.0 2026-04-03 Initial 2026-04-03 2026-04-03 openEuler SA Tool V1.0 2026-04-03 python-markdown security update An update for python-markdown is now available for openEuler-24.03-LTS This is a Python implementation of John Gruber’s Markdown. It is almost completely compliant with the reference implementation, though there are a few known issues. Security Fix(es): Python-Markdown version 3.8 contain a vulnerability where malformed HTML-like sequences can cause html.parser.HTMLParser to raise an unhandled AssertionError during Markdown parsing. Because Python-Markdown does not catch this exception, any application that processes attacker-controlled Markdown may crash. This enables remote, unauthenticated Denial of Service in web applications, documentation systems, CI/CD pipelines, and any service that renders untrusted Markdown. The issue was acknowledged by the vendor and fixed in version 3.8.1. This issue causes a remote Denial of Service in any application parsing untrusted Markdown, and can lead to Information Disclosure through uncaught exceptions.(CVE-2025-69534) An update for python-markdown is now available for openEuler-22.03-LTS-SP4/openEuler-24.03-LTS. openEuler Security has rated this update as having a security impact of high.
