Prior to 4.1.0, the addJS method in the jspdf Node.js build utilizes a shared module-scoped variable (text) to store JavaScript content. When used in a concurrent environment (e.g., a Node.js web server), this variable is shared across all requests. If multiple requests generate PDFs simultaneously, the JavaScript content intended for one user may be overwritten by a subsequent request before the document is generated. This results in Cross-User Data Leakage, where the PDF generated for User A contains the JavaScript payload (and any embedded sensitive data) intended for User B. Typically, this only affects server-side environments, although the same race conditions might occur if jsPDF runs client-side. The vulnerability has been fixed in jsPDF@4.1.0."}, {"lang": "es", "value": "jsPDF es una biblioteca para generar PDFs en JavaScript. Antes de la versi\u00f3n 4.1.0, el m\u00e9todo addJS en la compilaci\u00f3n de Node.js de jspdf utiliza una variable compartida con \u00e1mbito de m\u00f3dulo (text) para almacenar contenido JavaScript. Cuando se utiliza en un entorno concurrente (por ejemplo, un servidor web Node.js), esta variable se comparte entre todas las solicitudes. Si m\u00faltiples solicitudes generan PDFs simult\u00e1neamente, el contenido JavaScript destinado a un usuario puede ser sobrescrito por una solicitud subsiguiente antes de que se genere el documento. Esto resulta en una Fuga de Datos entre Usuarios (Cross-User Data Leakage), donde el PDF generado para el Usuario A contiene la carga \u00fatil de JavaScript (y cualquier dato sensible incrustado) destinada al Usuario B. T\u00edpicamente, esto solo afecta a entornos del lado del servidor, aunque las mismas condiciones de carrera podr\u00edan ocurrir si jsPDF se ejecuta del lado del cliente.
