      "value": "Jinja is an extensible templating engine. Prior to 3.1.5, An oversight in how the Jinja sandboxed environment detects calls to str.format allows an attacker that controls the content of a template to execute arbitrary Python code. To exploit the vulnerability, an attacker needs to control the content of a template. Whether that is the case depends on the type of application using Jinja. This vulnerability impacts users of applications which execute untrusted templates. Jinja's sandbox does catch calls to str.format and ensures they don't escape the sandbox. However, it's possible to store a reference to a malicious string's format method, then pass that to a filter that calls it. No such filters are built-in to Jinja, but could be present through custom filters in an application. After the fix, such indirect calls are also handled by the sandbox. This vulnerability is fixed in 3.1.5."

      "value": "Jinja es un motor de plantillas extensible. Antes de la versi\u00f3n 3.1.5, una supervisi\u00f3n de c\u00f3mo el entorno aislado de Jinja detecta llamadas a str.format permit\u00eda a un atacante que controlaba el contenido de una plantilla ejecutar c\u00f3digo Python arbitrario. Para aprovechar la vulnerabilidad, un atacante necesita controlar el contenido de una plantilla. Que ese sea el caso depende del tipo de aplicaci\u00f3n que utilice Jinja. Esta vulnerabilidad afecta a los usuarios de aplicaciones que ejecutan plantillas que no son de confianza. El sandbox de Jinja capta llamadas a str.format y garantiza que no escapen de la sandbox. Sin embargo, es posible almacenar una referencia al m\u00e9todo de formato de una cadena maliciosa y luego pasarla a un filtro que lo llame. Estos filtros no est\u00e1n integrados en Jinja, pero podr\u00edan estar presentes a trav\u00e9s de filtros personalizados en una aplicaci\u00f3n. Despu\u00e9s de la soluci\u00f3n, estas llamadas indirectas tambi\u00e9n son gestionadas por la sandbox. Esta vulnerabilidad se solucion\u00f3 en 3.1.5."
