CVE-2022-24758Network attack vector

Session hijacking via full-header error logging

Published Mar 31, 2022 · Updated Apr 23, 2025

Sensitive-data logging in Project Jupyter Jupyter Notebook before 6.4.10 allows local users to read authentication cookies from server logs. The notebook/log.py log_request function serializes every request header when most 5xx responses occur instead of limiting output to nonsensitive fields. Reading the server log does not require root access; a local user who can induce an error can recover a session cookie and access the server.
