{"apiVersion":"1.0","identifier":"CVE-2026-73415","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. This issue is fixed in versions 4.5.10 and 4.6.2.","publishedAt":"2026-08-12T20:17:56","lastModifiedAt":"2026-08-12T21:17:40","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73415","cvssScore":7.5,"cvssVector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00574,"riskScore":0.79,"affectedProduct":"jupyterlab","affectedVersions":"<4.5.10,<4.6.2","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73415","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73415","en":"https://www.redsauce.net/en/cves/CVE-2026-73415","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73415","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73415","de":"https://www.redsauce.net/de/cves/CVE-2026-73415","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73415","el":"https://www.redsauce.net/el/cves/CVE-2026-73415"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73415"}}
