Dear all,
until recently extra html files linked from html datasets got displayed with style information applied, but this seems to have changed. I did not investigate the change in detail, but is this a consequence of the backported https://docs.galaxyproject.org/en/master/releases/17.09_announce.html#cross-...
Is downloading the zipped data and opening it locally now the only way to view styled html?
Have a nice weekend, Wolfgang
Hi Wolfgang,
As a security measure, we added sanitization by default of content displayed as HTML. Local galaxy administrators can use the display whitelist (left side of the admin window) to configure 'safe' applications, which will then no longer be sanitized on display. Let me know if this doesn't solve the problem for you!

Maybe a dumb follow-up question, but I just don't know much about web server security:
Why does sanitization have to care about in-document style information?

No, it's a good question!
The primarily concern is malicious javascript which could be used to compromise a user's account or otherwise act on their behalf. Javascript is of course stripped out by the sanitizer, but it's also possible to embed javascript in CSS files (I think at this point only in older browsers), so to be safe we disable all that unless a tool is explicitly marked trusted.

I see! I've read a bit about the topic now and playing it safe like this makes sense.
Thanks again for the explanation, Wolfgang
