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
IPython (Interactive Python) is a command shell for interactive computing in multiple programming languages, originally developed for the Python programming language. Affected versions are subject to an arbitrary code execution vulnerability achieved by not properly managing cross user temporary files. This vulnerability allows one user to run code as another on the same machine. All users are advised to upgrade.

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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Vendor patch github.com →
Recommended fix High confidence

IPython 7.31.1 (for 7.x users), 8.0.1 (for 8.x users), or latest 8.x release

  1. Identify the current IPython version by running: pip show ipython or conda list ipython
  2. For pip users: Run 'pip install --upgrade ipython' to get the latest version in your current major series
  3. Alternatively, install a specific fixed version: pip install ipython==7.31.1 (for Python 3.8+) or pip install ipython==7.16.3 (for Python 3.7)
  4. For conda users: Run 'conda update ipython' or 'conda install ipython=7.31.1'
  5. After upgrading, verify the fix by checking the installed version: pip show ipython
  6. Restart any IPython kernels or notebooks to ensure the new version is active
Caveat Minimal risk - this is a security patch release; however, users on Python 2.7 or very old Python 3 versions may need to remain on IPython 5.x which may not receive patches
