Prior to 3.2.1, HTMLRenderer.heading() builds the opening &lt;hN&gt; tag by string-concatenating the id attribute value directly into the HTML — with no call to escape(), safe_entity(), or any other sanitisation function. A double-quote character &#34; in the id value terminates the attribute, allowing an attacker to inject arbitrary additional attributes (event handlers, src=, href=, etc.) into the heading element. This vulnerability is fixed in 3.2.1.</p> <p><strong>Affected:</strong> lepture mistune</p> <p>Mistune is a Python Markdown parser with renderers and plugins.
