Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Jupyter notebook is a web-based notebook environment for interactive computing. Prior to version 6.4.9, unauthorized actors can access sensitive information from server logs. Anytime a 5xx error is triggered, the auth cookie and other header values are recorded in Jupyter server logs by default. Considering these logs do not require root access, an attacker can monitor these logs, steal sensitive auth/cookie information, and gain access to the Jupyter server. Jupyter notebook version 6.4.x contains a patch for this issue. There are currently no known workarounds.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

In Jupyter Notebook versions prior to 6.4.9, unauthorized actors can access sensitive authentication information (cookies and headers) from server logs whenever a 5xx error occurs. Since these logs do not require root access, attackers can monitor them to steal auth credentials and gain unauthorized access to the Jupyter server.

MitigationUpgrade Jupyter Notebook to version 6.4.9 or later to apply the patch that prevents auth cookies and headers from being logged. There are no known workarounds.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Jupyter Notebook installed version
    Run `jupyter notebook --version` or check the package manager (e.g., `pip show notebook` or `conda list notebook`) to retrieve the installed version number
    Affected if The version displayed is earlier than 6.4.10 (e.g., 6.4.9, 6.4.8, etc.)
  2. Locate Jupyter Notebook log files
    Check the Jupyter configuration file or run `jupyter notebook --generate-config` and look for the `NotebookApp.log_file` setting, or search standard locations such as `~/.jupyter/` or system log directories for files named similarly to `jupyter.log` or `notebook.log`
    Affected if Log files exist and are stored in an accessible directory
  3. Inspect log files for authentication data in 5xx errors
    Open the identified log files and search for 5xx error entries (status codes 500, 502, 503, 504) using a command like `grep -E '5[0-9]{2}' <logfile>` or manually scan for error patterns
    Affected if Log entries containing 5xx errors show cookie values (e.g., session tokens) or authorization headers (e.g., bearer tokens)
  4. Verify log file permissions
    Check file permissions on the log files using `ls -la <logfile>` to determine if non-privileged users can read them
    Affected if Log files are readable by users other than the notebook server owner (e.g., permissions allow world-readable or group-readable access)

You are affected if Jupyter Notebook version is earlier than 6.4.10 AND log files exist with 5xx error entries containing authentication cookies or headers that are readable by unauthorized users.

Upgrade available Upgrade to 6.4.10 or later
Fixed in 6.4.10
Interim mitigation

Upgrade Jupyter Notebook to version 6.4.9 or later to apply the patch that prevents auth cookies and headers from being logged. There are no known workarounds.

Recommended fix High confidence

6.4.10 or later in the 6.4.x series

  1. Check current Jupyter notebook version using `jupyter notebook --version` or `pip show notebook`
  2. Upgrade Jupyter notebook to version 6.4.10 or later using `pip install --upgrade notebook`
  3. Verify the upgrade was successful by running `jupyter notebook --version`
  4. Ensure the version is 6.4.10 or higher to confirm the vulnerability is patched
Caveat Minimal expected; this is a security patch release with no known breaking changes
