{"cve":"CVE-2024-43805","nvd":{"published":"2024-08-28T20:15:07.963","modified":"2026-06-17T07:51:44.833","status":"Analyzed","description":"jupyterlab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. This vulnerability depends on user interaction by opening a malicious notebook with Markdown cells, or Markdown file using JupyterLab preview feature. A malicious user can access any data that the attacked user has access to as well as perform arbitrary requests acting as the attacked user. JupyterLab v3.6.8, v4.2.5 and Jupyter Notebook v7.2.2 have been patched to resolve this issue. Users are advised to upgrade. There is no workaround for the underlying DOM Clobbering susceptibility. However, select plugins can be disabled on deployments which cannot update in a timely fashion to minimise the risk. These are: 1. `@jupyterlab/mathjax-extension:plugin` - users will loose ability to preview mathematical equations. 2. `@jupyterlab/markdownviewer-extension:plugin` - users will loose ability to open Markdown previews. 3. `@jupyterlab/mathjax2-extension:plugin` (if installed with optional `jupyterlab-mathjax2` package) - an older version of the mathjax plugin for JupyterLab 4.x. To disable these extensions run: ```jupyter labextension disable @jupyterlab/markdownviewer-extension:plugin && jupyter labextension disable @jupyterlab/mathjax-extension:plugin && jupyter labextension disable @jupyterlab/mathjax2-extension:plugin ``` in bash.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/jupyterlab/jupyterlab/security/advisories/GHSA-9q39-rmj3-p4r2"],"products":["jupyter:jupyterlab","jupyter:notebook"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-43805","score":0.00399,"percentile":0.34165,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9q39-rmj3-p4r2","url":"https://osv.dev/vulnerability/GHSA-9q39-rmj3-p4r2","summary":"HTML injection in Jupyter Notebook and JupyterLab leading to DOM Clobbering","modified":"2026-07-13T16:43:05.974128183Z","packages":[{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":["<3.6.8"],"fixed":["3.6.8"]},{"ecosystem":"PyPI","name":"notebook","purl":"pkg:pypi/notebook","ranges":[">=7.0.0 <7.2.2"],"fixed":["7.2.2"]},{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":[">=4.0.0 <4.2.5"],"fixed":["4.2.5"]}]},{"id":"PYSEC-2026-1481","url":"https://osv.dev/vulnerability/PYSEC-2026-1481","summary":"HTML injection in Jupyter Notebook and JupyterLab leading to DOM Clobbering","modified":"2026-07-13T16:43:05.974128183Z","packages":[{"ecosystem":"PyPI","name":"notebook","purl":"pkg:pypi/notebook","ranges":[">=7.0.0 <7.2.2"],"fixed":["7.2.2"]}]},{"id":"PYSEC-2026-2536","url":"https://osv.dev/vulnerability/PYSEC-2026-2536","summary":"HTML injection in Jupyter Notebook and JupyterLab leading to DOM Clobbering","modified":"2026-07-13T16:43:05.974128183Z","packages":[{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":["<3.6.8",">=4.0.0 <4.2.5"],"fixed":["3.6.8","4.2.5"]}]}],"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).
