Prior to 4.6.2-1, JupyterLab Desktop exposed getServerInfo to the renderer without confirming that the current page still had the local Jupyter server origin. In a local managed session using JupyterLab before 4.4.8, an attacker can place a crafted MathJax link in an untrusted notebook. If a victim opens the notebook and clicks the link, the existing renderer navigates to an attacker-controlled site while retaining access to the preload bridge. The site can call getServerInfo to obtain the local server URL and authentication token, then use the Jupyter REST API to create and trust a notebook that executes arbitrary code as the victim. Users whose environment already uses JupyterLab 4.4.8 or later are unaffected because the corrected link handling breaks the first step of the chain. This vulnerability is fixed in 4.6.2-1.\nhttps://www.cve.org/CVERecord?id=CVE-2026-86044https://github.com/jupyterlab/jupyterlab-desktop/security/advisories/GHSA-2mr8-962v-wc67https://github.com/jupyterlab/jupyterlab-desktop/commit/7f8f64ae796efae77d106612c95f0edd6c5dc273https://github.com/jupyterlab/jupyterlab-desktop/releases/tag/v4.6.2-1#jupyterlab #jupyterlab-desktop#CVE_2026_86044#bot", "url": "https://infosec.exchange/users/cve/statuses/117571433191099383"}, {"timestamp": "2026-11-06T21:17:12.297Z", "date_only": false, "value": "2026-11-06T21:17:12.297", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-86044", "record": "FKIE_CVE-2026-86044", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-06T21:43:30.166Z", "date_only": false, "value": "2026-11-06T21:43:30.166395Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/dyq4tfcmydiwr", "record": "CVE-2026-86044", "field": "creation_timestamp", "uuid": "b1b0135a-c24f-47eb-b6d3-000eb96c1dc6", "content": "CVE-2026-86044 - JupyterLab Desktop: One-Click Jupyter Server Token Leak leading to Remote Code Execution\nCVE ID : CVE-2026-86044\n \n Published : 6 novembre 2026 20:30 | 37\u00a0minutes ago\n \n Description : JupyterLab Desktop is the cross-platform desktop application for JupyterLab....", "url": "https://bsky.app/profile/cve.skyfleet.blue/post/dyq4tfcmydiwr"}, {"timestamp": "2026-11-06T21:46:51.305Z", "date_only": false, "value": "2026-11-06T21:46:51.305112Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/thehackerwire.bsky.social/post/3mzoeaeu6k32j", "record": "CVE-2026-86044", "field": "creation_timestamp", "uuid": "11aaac4f-e0d6-4a3e-8a64-8ecd4e386bae", "content": "\ud83d\udd34 CVE-2026-86044 - Critical (9.6)\n\nJupyterLab Desktop is the cross-platform desktop application for JupyterLab.
