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-2026-73415 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jupyterlab (Bitnami): affected all versions; fixed in 4.5.10, 4.6.2\n- jupyterlab (PyPI): affected all versions; fixed in 4.5.10, 4.6.2\n- jupyterlab (PyPI): affected all versions; fixed in 4.5.10\n- jupyterlab (PyPI): affected all versions; fixed in 4.5.10\n- jupyterlab (PyPI): affected from 4.6.0; fixed in 4.6.2\n- jupyterlab (PyPI): affected from 4.6.0; fixed in 4.6.2\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-2026-73415/ (Markdown: https://insights.sbomify.com/CVE-2026-73415/index.md)","id":"CVE-2026-73415","markdown":"https://insights.sbomify.com/CVE-2026-73415/index.md","name":"CVE-2026-73415","record":{"aliases":["BIT-jupyterlab-2026-73415","CLEANSTART-2026-SP63769","DEBIAN-CVE-2026-73415","GHSA-gx64-gj6p-pc4c","PYSEC-2026-3671","UBUNTU-CVE-2026-73415"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JupyterLab","requires_auth":"none","summary":"Attackers can execute arbitrary code on the JupyterLab server by tricking users into opening a malicious SVG image in a new tab.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"jupyterlab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. Prior to 4.5.10 and 4.6.2, in packages/imageviewer/src/widget.ts, JupyterLab's ImageViewer uses URL.createObjectURL for a specially crafted SVG image and revokes the blob URL too early, allowing the image to retain an executable same-origin context when it is opened through the image viewer and then opened in a new browser tab. The resulting cross-site scripting can be used to execute arbitrary code on the JupyterLab server.
