      "value": "Joplin is a free, open source note taking and to-do application. A Cross-site Scripting (XSS) vulnerability allows pasting untrusted data into the rich text editor to execute arbitrary code. HTML pasted into the rich text editor is not sanitized (or not sanitized properly). As such, the `onload` attribute of pasted images can execute arbitrary code. Because the TinyMCE editor frame does not use the `sandbox` attribute, such scripts can access NodeJS's `require` through the `top` variable. From this, an attacker can run arbitrary commands. This issue has been addressed in version 2.12.10 and users are advised to upgrade. There are no known workarounds for this vulnerability."

Una vulnerabilidad de Cross-Site Scripting (XSS) permite pegar datos que no son de confianza en el editor de texto enriquecido para ejecutar código arbitrario. El HTML pegado en el editor de texto enriquecido no se sanitiza (o no se sanitiza correctamente). Como tal, el atributo \"onload\" de las imágenes pegadas puede ejecutar código arbitrario. Debido a que el marco del editor TinyMCE no utiliza el atributo `sandbox`, dichos scripts pueden acceder al `require` de NodeJS a través de la variable `top`. A partir de esto, un atacante puede ejecutar comandos arbitrarios. Este problema se solucionó en la versión 2.12.10 y se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad."
