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. This issue is fixed in versions 4.5.10 and 4.6.2.","severity":{"version":"4.0","score":7.5,"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","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-12","score":0.00737,"percentile":0.54996,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-79"],"published":"2026-07-22T23:14:44Z","modified":"2026-10-28T02:30:52Z","fixes":[{"ecosystem":"PyPI","package":"jupyterlab","fixed_in":["4.6.2","4.5.10"],"sources":["ghsa","osv"]},{"ecosystem":"Bitnami","package":"jupyterlab","fixed_in":["4.5.10","4.6.2"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"jupyterlab","fixed_in":["4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-4"],"sources":["osv"]}],"affected":[{"source":"ghsa","ecosystem":"PyPI","package":"jupyterlab","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.6.0"},{"last_affected":"4.6.1"},{"fixed":"4.6.2"}]}]},{"source":"ghsa","ecosystem":"PyPI","package":"jupyterlab","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.5.9"},{"fixed":"4.5.10"}]}]},{"source":"osv","ecosystem":"Bitnami","package":"jupyterlab","ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.5.10"},{"introduced":"4.6.0"},{"fixed":"4.6.2"}]}]},{"source":"osv","ecosystem":"Debian:13","package":"jupyterlab","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.11+ds1+~cs11.25.27-7","4.0.11+ds1+~cs11.25.27-8","4.0.11+ds1+~cs11.25.27-9","4.0.11+ds2+~cs11.25.27-1","4.0.11+ds2+~cs11.25.27-3","4.0.11+ds3+~cs11.25.27-1","4.0.11+ds4+~cs11.25.27-1","4.0.11+ds4+~cs11.25.27-2","4.0.11+ds4+~cs11.25.27-3","4.0.11+ds4+~cs11.25.27-4","4.0.11+ds5+~cs11.25.27-1","4.0.13+ds1+~2.0.1+~cs1.4.4-1","4.1.3+ds1+~2.0.1+~0.15.3+~cs1.4.4-1","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-1","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-2","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-3","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-4","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-5","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-6","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-7","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-8","4.4.1+ds1+~3.0.5+~0.16.6+~cs1.4.4-1","4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-1","4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-2","4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-3","4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-4","4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-5","4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-6","4.4.8+ds1+~3.1.0+~0.16.6+~cs1.4.4-1"]},{"source":"osv","ecosystem":"Debian:14","package":"jupyterlab","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-4"}]}],"versions":["4.0.11+ds1+~cs11.25.27-7","4.0.11+ds1+~cs11.25.27-8","4.0.11+ds1+~cs11.25.27-9","4.0.11+ds2+~cs11.25.27-1","4.0.11+ds2+~cs11.25.27-3","4.0.11+ds3+~cs11.25.27-1","4.0.11+ds4+~cs11.25.27-1","4.0.11+ds4+~cs11.25.27-2","4.0.11+ds4+~cs11.25.27-3","4.0.11+ds4+~cs11.25.27-4","4.0.11+ds5+~cs11.25.27-1","4.0.13+ds1+~2.0.1+~cs1.4.4-1","4.1.3+ds1+~2.0.1+~0.15.3+~cs1.4.4-1","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-1","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-2","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-3","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-4","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-5","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-6","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-7","4.1.8+ds1+~2.0.1+~0.15.3+~cs1.4.4-8","4.4.1+ds1+~3.0.5+~0.16.6+~cs1.4.4-1","4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-1","4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-2","4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-3","4.4.8+ds1+~3.1.0+~0.16.6+~cs1.4.4-1"]},{"source":"osv","ecosystem":"PyPI","package":"jupyterlab","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.6.0"},{"fixed":"4.6.2"}]}],"versions":["4.6.0","4.6.1"]},{"source":"osv","ecosystem":"PyPI","package":"jupyterlab","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.5.10"}]}],"versions":["0.0.1","0.0.10","0.0.13","0.0.2","0.0.3","0.0.4","0.0.5","0.0.6","0.0.7","0.0.8","0.0.9","0.1.1","0.1.2","0.10.0","0.11.0","0.11.1","0.11.2","0.11.3","0.12.0","0.12.1","0.13.0","0.13.1","0.13.2","0.14.0","0.15.0","0.15.1","0.16.0","0.16.2","0.17.0","0.17.1","0.17.2","0.17.4","0.17.5","0.18.0","0.18.0.dev1","0.18.1","0.19.0","0.2.0","0.20.0","0.20.0rc1","0.20.1","0.20.2","0.20.3","0.20.4","0.21.0","0.21.0rc1","0.21.0rc2","0.21.0rc3","0.21.0rc4","0.21.0rc5","0.22.0","0.22.0rc0","0.22.1","0.23.0","0.23.0rc0","0.23.0rc1","0.23.1","0.23.2","0.24.0","0.24.0rc0","0.24.0rc1","0.24.0rc2","0.24.1","0.25.0","0.25.0rc0","0.25.0rc1","0.25.1","0.25.2","0.25.2rc0","0.26.0","0.26.0rc0","0.26.0rc1","0.26.1","0.26.2","0.26.3","0.26.4","0.26.5","0.27.0","0.27.0rc0","0.27.0rc1","0.27.0rc2","0.27.0rc3","0.27.0rc4","0.27.0rc5","0.27.1","0.27.2","0.28.0","0.28.0rc0","0.28.0rc1","0.28.0rc2","0.28.0rc3","0.28.1","0.28.10","0.28.11","0.28.12","0.28.13","0.28.14","0.28.15","0.28.2","0.28.3","0.28.4","0.28.5","0.28.6","0.28.7","0.28.8","0.29.0","0.29.0rc0","0.29.1","0.29.2","0.3.0","0.30.0","0.30.0rc0","0.30.0rc1","0.30.1","0.30.2","0.30.3","0.30.4","0.30.5","0.30.6","0.31.0","0.31.0rc0","0.31.0rc1","0.31.0rc2","0.31.1","0.31
