CVE-2024-39700Public exploitNetwork attack vector

Repository compromise via untrusted pull-request workflow execution

Published Jul 16, 2024 · Updated Aug 16, 2024

Code injection in Project Jupyter JupyterLab Extension Template before 4.3.3 allows remote authenticated users to execute code in GitHub Actions. The generated update-integration-tests.yml workflow checks out code from an untrusted pull request after an issue comment and runs its scripts with a privileged GITHUB_TOKEN and repository secrets. An attacker needs a GitHub account and a pull request, and execution can expose secrets or permit unauthorized repository changes.
