JupyterLab: Image viewer allows XSS when opening malicious image in new browser tab
JupyterLab's image viewer allows for cross-site scripting (XSS) when a specially-crafted image file is opened through the image viewer and then opened in a new tab. This XSS issue can be used to cause remote code execution (RCE) on the JupyterLab server. ### Impact This vulnerability allows for arbitrary code execution. ### Patches JupyterLab [`v4.6.2`](https://github.com/jupyterlab/jupyterlab/releases/tag/v4.6.2) and [`v4.5.10`](https://github.com/jupyterlab/jupyterlab/releases/tag/v4.5.10) contain the patch. ### Workarounds Disable the image viewer plugin: ``` jupyter labextension disable @jupyterlab/imageviewer-extension:plugin ``` Confirm with: ``` jupyter labextension list ```
