Repositories created using this template with `test` option include `update-integration-tests.yml` workflow which has an RCE vulnerability. Extension authors hosting their code on GitHub are urged to upgrade the template to the latest version. Users who made changes to `update-integration-tests.yml`, accept overwriting of this file and re-apply your changes later. Users may wish to temporarily disable GitHub Actions while working on the upgrade. We recommend rebasing all open pull requests from untrusted users as actions may run using the version from the `main` branch at the time when the pull request was created. Users who are upgrading from template version prior to 4.3.0 may wish to leave out proposed changes to the release workflow for now as it requires additional configuration.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-94"],"references":["https://github.com/jupyterlab/extension-template/commit/035e78c1c65bcedee97c95bb683abe59c96bc4e6","https://github.com/jupyterlab/extension-template/security/advisories/GHSA-45gq-v5wm-82wg","https://github.com/jupyterlab/extension-template/commit/035e78c1c65bcedee97c95bb683abe59c96bc4e6","https://github.com/jupyterlab/extension-template/security/advisories/GHSA-45gq-v5wm-82wg"],"products":["jupyter:jupyterlab"],"source":"nvd","synced_at":"2026-10-19T21:52:42.518321223+00:00"},"epss":{"cve":"CVE-2024-39700","score":0.01092,"percentile":0.65425,"date":"2026-10-31"},"kev":null,"osv":[{"id":"PYSEC-2024-322","url":"https://osv.dev/vulnerability/PYSEC-2024-322","summary":"","modified":"2026-07-13T07:26:34.864535687Z","packages":[{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":["<4.3.0"],"fixed":["4.3.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
