@kong/markdownTL;DR
Affected versions of this package are vulnerable to cross-site scripting (XSS) due to insufficient sanitization of user-controlled content. The rendering logic processes definitions containing embedded HTML without properly filtering dangerous attributes, allowing attacker-supplied markup to execute arbitrary JavaScript in the browser. An attacker able to inject crafted content can trigger script execution, leading to full page takeover in affected contexts.
