Descriptions

Jupyter Server before version 1.0.6 has an Open redirect vulnerability. A maliciously crafted link to a jupyter server could redirect the browser to a different website. All jupyter servers are technically affected, however, these maliciously crafted links can only be reasonably made for known jupyter server hosts. A link to your jupyter server may appear safe, but ultimately redirect to a spoofed server on the public internet.

Jupyter Server anterior a versión 1.0.6, presenta una vulnerabilidad de redireccionamiento abierto. Un enlace creado con fines maliciosos en un servidor jupyter podría redireccionar el navegador a un sitio web diferente. Todos los servidores jupyter están afectados técnicamente; sin embargo, estos enlaces creados con fines maliciosos solo se pueden crear de forma razonable para hosts de servidores jupyter conocidos. Un enlace a su servidor jupyter puede parecer seguro, pero en última instancia redirecciona a un servidor falsificado en la internet pública
