Hi, The following vulnerability was published for jupyter-server. CVE-2022-29241[0]: | Jupyter Server provides the backend (i.e. the core services, APIs, and | REST endpoints) for Jupyter web applications like Jupyter Notebook. | Prior to version 1.17.1, if notebook server is started with a value of | `root_dir` that contains the starting user's home directory, then the | underlying REST API can be used to leak the access token assigned at | start time by guessing/brute forcing the PID of the jupyter server. | While this requires an authenticated user session, this URL can be | used from a cross-site scripting payload or from a hooked or otherwise | compromised browser to leak this access token to a malicious third | party. This token can be used along with the REST API to interact with | Jupyter services/notebooks such as modifying or overwriting critical | files, such as .bashrc or .ssh/authorized_keys, allowing a malicious | user to read potentially sensitive data and possibly gain control of | the impacted system. This issue is patched in version 1.17.1. https://github.com/jupyter-server/jupyter_server/security/advisories/GHSA-q874-g24w-4q9g If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
