Technical details

This is a Cross-site Scripting (CWE-79) vulnerability in editor.md version 1.5.0 and earlier, caused by insufficient sanitization of markdown input before rendering to HTML. An attacker can inject malicious HTML and JavaScript through markdown text—for example, embedding an img tag with an onerror event handler that executes arbitrary code. The vulnerability is triggered when a user edits or views markdown containing the payload, with no authentication required. The attack relies on user interaction (viewing the crafted markdown in the editor) but affects the security context of the application. Patches are available in versions after 1.5.0.
