What is CVE-2024-28179?

Jupyter Server Proxy versions prior to 3.2.3 and 4.1.1 contain a vulnerability that permits unauthorized users to connect to websocket endpoints. This flaw occurs because user authentication checks are not performed properly when proxying websockets. Consequently, attackers with network access to the Jupyter server can exploit this vulnerability, potentially leading to the execution of arbitrary code on the server. It is critical for users to upgrade to the patched versions to mitigate this risk. Notably, instances that do not leverage websockets are unaffected by this issue.
