CVE-2026-308385.1

This vulnerability allows an attacker to inject malicious HTML, like a script tag, into applications that use a specific Markdown parser to handle user input, potentially leading to cross-site scripting (XSS) attacks. It can be exploited by cleverly inserting whitespace in disallowed HTML tags, and it affects any application relying on the parser's built-in sanitization without additional protections.
