ParameterPositionPathDescriptionCWE
.ipynb file contentnested/-/api/sanitize_ipynbThe server-side sanitization of .ipynb previews via this endpoint is insufficient because the client-side re-rendering of the content (specifically elements with the .nb-markdown-cell class) allows for the regeneration of javascript: links, leading to Stored XSS.CWE-79
