Markdown-based comments in the ZenUML diagram syntax are susceptible to Cross-site Scripting (XSS). The comment feature allows the user to attach small notes for reference. This feature allows the user to enter in their comment in markdown comment, allowing them to use common markdown features, such as `**` for bolded text. However, the markdown text is currently not sanitized before rendering, allowing an attacker to enter a malicious payload for the comment which leads to XSS. This puts existing applications that use ZenUML unsandboxed at risk of arbitrary JavaScript execution when rendering user-controlled diagrams. This vulnerability was patched in version 3.23.25,"}, {"lang": "es", "value": "ZenUML es una herramienta de diagramaci\u00f3n basada en JavaScript que no requiere servidor y utiliza definiciones de texto inspiradas en Markdown y un renderizador para crear y modificar diagramas de secuencia.
