CVE-2026-44727: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in jupyter-server jupyter_serverCVE-2026-44727 0 A critical cross-site scripting (XSS) vulnerability exists in jupyter_server prior to version 2.20. The nbconvert HTTP handlers render user-authored notebook HTML without a sandbox directive in the Content-Security-Policy, combined with default non-sanitizing behavior of nbconvert.HTMLExporter. This allows stored XSS that can lead to cookie access, full API authority, and kernel remote code execution. The vulnerability is fixed in version 2.20.
