      "value": "Fabric.js is a Javascript HTML5 canvas library. Prior to version 7.2.0, Fabric.js applies `escapeXml()` to text content during SVG export (`src/shapes/Text/TextSVGExportMixin.ts:186`) but fails to apply it to other user-controlled string values that are interpolated into SVG attribute markup. When attacker-controlled JSON is loaded via `loadFromJSON()` and later exported via `toSVG()`, the unescaped values break out of XML attributes and inject arbitrary SVG elements including event handlers. Any application that accepts user-supplied JSON (via `loadFromJSON()`, collaborative sharing, import features, CMS plugins) and renders the `toSVG()` output in a browser context (SVG preview, export download rendered in-page, email template, embed) is vulnerable to stored XSS. An attacker can execute arbitrary JavaScript in the victim's browser session. Version 7.2.0 contains a fix."

Antes de la versión 7.2.0, Fabric.js aplica `escapeXml()` al contenido de texto durante la exportación SVG (`src/shapes/Text/TextSVGExportMixin.ts:186`) pero no lo aplica a otros valores de la cadena controlados por el usuario, que se interpolan en el marcado de atributos SVG. Cuando se carga un JSON controlado por el atacante a través de `loadFromJSON()` y luego se exporta a través de `toSVG()`, los valores sin escapar se salen de los atributos XML e inyectan elementos SVG arbitrarios, incluidos los controladores de eventos. Cualquier aplicación que acepte JSON proporcionados por el usuario (a través de `loadFromJSON()`, uso compartido colaborativo, funciones de importación, complementos de CMS) y renderice la salida de `toSVG()` en un contexto de navegador (vista previa SVG, descarga de exportación renderizada en la página, plantilla de correo electrónico, incrustación) es vulnerable a XSS almacenado. Un atacante puede ejecutar JavaScript arbitrario en la sesión del navegador de la víctima. La versión 7.2.0 contiene una solución."
