Cross-site Scripting in invenio-previewer
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:
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.
