Plain English Summary

AI-powered analysis for quick understanding

An attacker can crash applications that use Python-Markdown by sending specially crafted Markdown content, which causes the program to fail without handling the error. This vulnerability affects any system that processes untrusted Markdown, such as web applications or documentation tools, and can lead to service outages.

Technical Description

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.
