{"cve":"CVE-2025-59842","nvd":{"published":"2025-09-26T16:15:48.890","modified":"2026-10-19T16:10:00.260","status":"Analyzed","description":"jupyterlab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. Prior to version 4.4.8, links generated with LaTeX typesetters in Markdown files and Markdown cells in JupyterLab and Jupyter Notebook did not include the noopener attribute. This is deemed to have no impact on the default installations. Theoretically users of third-party LaTeX-rendering extensions could find themselves vulnerable to reverse tabnabbing attacks if links generated by those extensions included target=_blank (no such extensions are known at time of writing) and they were to click on a link generated in LaTeX (typically visibly different from other links). This issue has been patched in version 4.4.8.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":2.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-1022"],"references":["https://github.com/jupyterlab/jupyterlab/commit/88ef373039a8cc09f27d3814382a512d9033675c","https://github.com/jupyterlab/jupyterlab/security/advisories/GHSA-vvfj-2jqx-52jm"],"products":["jupyter:jupyterlab"],"source":"nvd","synced_at":"2026-10-19T22:10:08.713834912+00:00"},"epss":{"cve":"CVE-2025-59842","score":0.0024,"percentile":0.14945,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-vvfj-2jqx-52jm","url":"https://osv.dev/vulnerability/GHSA-vvfj-2jqx-52jm","summary":"JupyterLab LaTeX typesetter links did not enforce `noopener` attribute","modified":"2026-09-10T03:50:28.901132283Z","packages":[{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":["<4.4.8"],"fixed":["4.4.8"]}]},{"id":"PYSEC-2026-1482","url":"https://osv.dev/vulnerability/PYSEC-2026-1482","summary":"JupyterLab LaTeX typesetter links did not enforce `noopener` attribute","modified":"2026-07-07T17:57:38.072715082Z","packages":[{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":["<4.4.8"],"fixed":["4.4.8"]}]}],"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).
