Description Sam Fowler 2018-03-21 01:25:40 UTC

n Jupyter Notebook before 5.4.1, a maliciously forged notebook file can bypass sanitization to execute JavaScript in the notebook context. Specifically, invalid HTML is 'fixed' by jQuery after sanitization, making it dangerous.

This was fixed in Fedora a while ago. Should this be closed?
