The adr-viewer component of Mistune's HTMLRenderer has a vulnerability (CVE-2026-44897) where the heading ID attribute is inserted into HTML without escaping. This allows an attacker controlling heading text to inject arbitrary HTML attributes, including event handlers, leading to cross-site scripting (XSS). The default behavior uses safe auto-generated IDs, but when a custom heading_id callback returns raw heading text, the vulnerability is triggered. A proof of concept demonstrates injecting a mouseover event that executes JavaScript. A patch is available to address this issue.
