An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-102832 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jupyterlab (PyPI): affected from 4.5.7; fixed in 4.5.11\n- jupyterlab (PyPI): affected from 4.5.7; fixed in 4.5.11\n- jupyterlab (PyPI): affected from 4.6.0; fixed in 4.6.4\n- jupyterlab (PyPI): affected from 4.6.0; fixed in 4.6.4\n- jupyterlite-core (PyPI): affected from 0.7.5; fixed in 0.8.4\n- jupyterlite-core (PyPI): affected from 0.7.5; fixed in 0.8.4\n- notebook (PyPI): affected from 7.5.6; fixed in 7.6.3\n- notebook (PyPI): affected from 7.5.6; fixed in 7.6.3\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-102832/ (Markdown: https://insights.sbomify.com/CVE-2026-102832/index.md)","id":"CVE-2026-102832","markdown":"https://insights.sbomify.com/CVE-2026-102832/index.md","name":"CVE-2026-102832","record":{"aliases":["GHSA-jwrc-gm9j-263p","MINI-55w7-x268-8h65","MINI-w2jj-869g-mh6x","UBUNTU-CVE-2026-102832"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JupyterLab","requires_auth":"none","summary":"Attackers can bypass trust prompts by switching documents during confirmation, allowing untrusted code execution in JupyterLab.","user_interaction":"required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"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.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"JupyterLab: Command link trust prompt in JupyterLab can trust a document other than the one clicked","id":"CVE-2026-102832","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":8,"n_references":6,"next":{"headline":"JavaCV: Integer Overflow in IPCameraFrameGrabber Causes Infinite-Loop DoS","id":"CVE-2026-102834"},"packages":[{"ecosystem":"PyPI","fixed":["4.5.11"],"introduced":["4.5.7"],"last_affected":[],"package":"jupyterlab","purl":null,"source":"GHSA-jwrc-gm9j-263p"},{"ecosystem":"PyPI","fixed":["4.5.11"],"introduced":["4.5.7"],"last_affected":[],"package":"jupyterlab","purl":"pkg:pypi/jupyterlab","source":"GHSA-jwrc-gm9j-263p"},{"ecosystem":"PyPI","fixed":["4.6.4"],"introduced":["4.6.0"],"last_affected":[],"package":"jupyterlab","purl":null,"source":"GHSA-jwrc-gm9j-263p"},{"ecosystem":"PyPI","fixed":["4.6.4"],"introduced":["4.6.0"],"last_affected":[],"package":"jupyterlab","purl":"pkg:pypi/jupyterlab","source":"GHSA-jwrc-gm9j-263p"},{"ecosystem":"PyPI","fixed":["0.8.4"],"introduced":["0.7.5"],"last_affected":[],"package":"jupyterlite-core","purl":null,"source":"GHSA-jwrc-gm9j-263p"},{"ecosystem":"PyPI","fixed":["0.8.4"],"introduced":["0.7.5"],"last_affected":[],"package":"jupyterlite-core","purl":"pkg:pypi/jupyterlite-core","source":"GHSA-jwrc-gm9j-263p"},{"ecosystem":"PyPI","fixed":["7.6.3"],"introduced":["7.5.6"],"last_affected":[],"package":"notebook","purl":null,"source":"GHSA-jwrc-gm9j-263p"},{"ecosystem":"PyPI","fixed":["7.6.3"],"introduced":["7.5.6"],"last_affected":[],"package":"notebook","purl":"pkg:pypi/notebook","source":"GHSA-jwrc-gm9j-263p"}],"prev":{"headline":"JupyterLab: Cross-site scripting (XSS) in JupyterLab via notebook cells pasted from the system clipboard","id":"CVE-2026-102831"},"products":["jupyterlab","jupyterlite-core","notebook"],"published":"2026-10-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-13","vendors":["jupyterlab"]},"summary":"Attackers can bypass trust prompts by switching documents during confirmation, allowing untrusted code execution in JupyterLab.","url":"https://insights.sbomify.com/CVE-2026-102832/"}
