{"cve":"CVE-2026-102832","nvd":{"published":"2026-10-13T16:17:09.970","modified":"2026-10-16T16:00:33.533","status":"Awaiting Analysis","description":"JupyterLab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. From 4.5.7 until 4.5.11 and 4.6.4, the markdownviewer:trust and notebook:trust command-link handlers use tracker.currentWidget to resolve the current Markdown viewer or notebook when the user answers rather than retaining the document whose command button was clicked. If another document becomes current while the prompt is open and the user chooses Trust, JupyterLab marks the second document trusted while leaving the clicked document untrusted. Later command buttons in the incorrectly trusted document run without a prompt, and trusting a notebook marks all cells trusted, saves unsaved edits, and persists the server signature to disk. Applications that bundle JupyterLab, including affected Notebook and JupyterLite releases, inherit the behavior. This issue is fixed in versions 4.5.11 and 4.6.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","score":4.2},"cwes":["CWE-367","CWE-863"],"references":["https://github.com/jupyterlab/jupyterlab/commit/0fc18ab4ef67e431a8f6560e387193baf786c70a","https://github.com/jupyterlab/jupyterlab/commit/b64bc88b8ca034cf158604a5cc48ca9170ea453b","https://github.com/jupyterlab/jupyterlab/commit/f7e5f9803fdf2aaaa0e9bfb9cc73386a8cc5f0b2","https://github.com/jupyterlab/jupyterlab/releases/tag/v4.5.11","https://github.com/jupyterlab/jupyterlab/releases/tag/v4.6.4"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-102832","score":0.00143,"percentile":0.03556,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jwrc-gm9j-263p","url":"https://osv.dev/vulnerability/GHSA-jwrc-gm9j-263p","summary":"JupyterLab: Command link trust prompt in JupyterLab can trust a document other than the one clicked","modified":"2026-10-15T20:30:07.110246844Z","packages":[{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":[">=4.6.0 <4.6.4"],"fixed":["4.6.4"]},{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":[">=4.5.7 <4.5.11"],"fixed":["4.5.11"]},{"ecosystem":"PyPI","name":"notebook","purl":"pkg:pypi/notebook","ranges":[">=7.5.6 <7.6.3"],"fixed":["7.6.3"]},{"ecosystem":"PyPI","name":"jupyterlite-core","purl":"pkg:pypi/jupyterlite-core","ranges":[">=0.7.5 <0.8.4"],"fixed":["0.8.4"]}]}],"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).
