CyberRota Analysis
AI-GeneratedJupyterLab versions 4.5.0 to 4.5.11, 4.6.4, and Notebook versions 7.5.0 to 7.6.3 are vulnerable to a high-severity issue where the system clipboard cell-paste functionality allows untrusted JSON to be executed as trusted HTML output, potentially leading to unauthorized script execution in the authenticated environment. This vulnerability poses a significant risk to users who rely on these versions for interactive computing, particularly those with useSystemClipboardForCells enabled and pasteCodeCellsWithoutOutput disabled. Organizations using affected JupyterLab or Notebook versions should prioritize updating to the patched releases to mitigate this security risk.

Original NVD Description
JupyterLab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. From JupyterLab 4.5.0 until 4.5.11 and 4.6.4, from Notebook 7.5.0 until 7.6.3, and from JupyterLite Core 0.7.0 until 0.8.4, the system clipboard cell-paste path accepts attacker-controlled cell JSON without clearing metadata.trusted. When useSystemClipboardForCells is active and pasteCodeCellsWithoutOutput is disabled, a pasted code cell can mark HTML output as trusted, bypass output sanitization, and execute script in the authenticated JupyterLab origin without executing the cell. Markdown and raw cells are not affected because their output is sanitized. This issue is fixed in JupyterLab 4.5.11 and 4.6.4, Notebook 7.6.3, and JupyterLite Core 0.8.4.
