      "value": "jQuery Terminal Emulator is a plugin for creating command line interpreters in your applications. Versions prior to 2.31.1 contain a low impact and limited cross-site scripting (XSS) vulnerability. The code for XSS payload is always visible, but an attacker can use other techniques to hide the code the victim sees. If the application uses the `execHash` option and executes code from URL, the attacker can use this URL to execute their code. The scope is limited because the javascript attribute used is added to span tag, so no automatic execution like with `onerror` on images is possible. This issue is fixed in version 2.31.1. As a workaround, the user can use formatting that wrap whole user input and its no op. The code for this workaround is available in the GitHub Security Advisory. The fix will only work when user of the library is not using different formatters (e.g. to highlight code in different way)."

      "value": "jQuery Terminal Emulator es un plugin para crear int\u00e9rpretes de l\u00ednea de comandos en sus aplicaciones. Las versiones anteriores a 2.31.1 contienen una vulnerabilidad de tipo cross-site scripting (XSS) de bajo impacto y limitada. El c\u00f3digo de la carga \u00fatil de tipo XSS es siempre visible, pero un atacante puede usar otras t\u00e9cnicas para ocultar el c\u00f3digo que visualiza la v\u00edctima. Si la aplicaci\u00f3n usa la opci\u00f3n \"execHash\" y ejecuta c\u00f3digo desde la URL, el atacante puede usar esta URL para ejecutar su c\u00f3digo. El alcance es limitado porque el atributo javascript usado es a\u00f1adido a la etiqueta span, por lo que no es posible una ejecuci\u00f3n autom\u00e1tica como con \"onerror\" en im\u00e1genes. Este problema se ha corregido en versi\u00f3n 2.31.1. Como soluci\u00f3n, el usuario puede usar un formato que envuelva toda la entrada del usuario y que no sea op. El c\u00f3digo de esta soluci\u00f3n est\u00e1 disponible en el aviso de seguridad de GitHub. La correcci\u00f3n s\u00f3lo funcionar\u00e1 cuando el usuario de la biblioteca no est\u00e9 usando diferentes formateadores (por ejemplo, para resaltar el c\u00f3digo de manera diferente).\n"
