**Name of the Vulnerable Software and Affected Versions** python-markdownify (aka markdownify) versions prior to 0.14.1 **Description** The issue allows large headline prefixes, such as <h9999999>, in addition to the standard <h1> through <h6> tags.

As a temporary workaround, consider restricting the use of large headline prefixes to minimize the risk of excessive memory consumption.
