## Cross-Site Scripting (XSS) vulnerability in JSON, Markdown and iPython Notebook previewers

### Impact Several Cross-Site Scripting (XSS) vulnerabilities have been found in the JSON, Markdown and iPython Notebook previewers. The vulnerabilities would allow a malicous user to upload a JSON, Markdown or Notebook file with embedded scripts that would be executed by a victims browser.

### Patches Invenio-Previewer v1.0.0a12 fixes the issue.

### Workarounds You can remediate the vulnerability without upgrading by disabling the affected previewers. You do this by adding the following to your configuration:

```python PREVIEWER_PREFERENCE = [ 'csv_dthreejs', 'simple_image', # 'json_prismjs', 'xml_prismjs', # 'mistune', 'pdfjs', # 'ipynb', 'zip', ] ```

Afterwards, you should not be able to preview JSON, Markdown or iPython Notebook files.
