ipython is vulnerable to Cross-Site Scripting (XSS)

Cross-Site Scripting (XSS)

TL;DR

IPython display helpers (Image, Video, Audio, IFrame, YouTubeVideo/VimeoVideo/ScribdDocument, and FileLinks) interpolated caller-supplied URLs, dimensions, element IDs, and on-disk file names into HTML attributes without escaping. A quote in those values closes the attribute and the remainder is parsed as markup, so a crafted value such as YouTubeVideo('abc"><script>') injects tags into notebook HTML output. The fix HTML-escapes these interpolated values before they are written into attributes.

How do I fix this?

Upgrade the ipython library to the patch version.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and render display objects whose URL, ID, dimensions, or file names can be influenced by untrusted input (including shared notebooks and FileLinks over attacker-writable directories).
