Re: [Wikitech-l] [Social-media] Improving the security of our users on Wikimedia sites
2015-04-27 18:51 GMT+03:00 Chris Steipp cste...@wikimedia.org: Hi Strainu, Thanks for the additional information Chris! We were trying to balance how much data vs summary information to give to people, but you can find the issues vs. resolution table here: https://www.mediawiki.org/wiki/Wikimedia_Security_Team/Check/iSEC_Assessment_2014 I was happy to see that some of the issues found by iSEC was previously identified in-house. However, I couldn't help noticing that https://phabricator.wikimedia.org/T64685 lingered for almost an year (or more, I'm not sure if the bugzilla import kept the dates) and the patch was only merged after this report found the bug as well. We all know the WMF is slow in merging patches, especially from outsiders, but shouldn't you have *some* guidelines (or preferably rules) on the time that a security bug can stay opened? I'm not trying to start yet another endless fight between WMF staff and the community, but the tendency in the last few years has been for the researchers to release the vulnerabilities after a certain time regardless if the software has been patched or not. Seeing MW exploits in the wild and knowing that developers had a chance to fix them and didn't does not help WMF's image. Regards, Strainu For the issue you pointed out in particular, we have https://phabricator.wikimedia.org/T85856 where you can follow the discussion. The end result was that this was a low severity issue, we're definitely not going to do away with user javascript, instead we may add a warning if we can find a useful UX experience for the user.

Re: [Wikitech-l] [Social-media] Improving the security of our users on Wikimedia sites
Let me just say that removing custom JS from Wikimedia sites would cause the mother of all shitstorms amongst the old hands editors, including Yours Truly. It would make the German Wikipedia resistance to the Media Viewer seem like a mild, slightly fragrant breeze. I do not believe the Foundation would actually consider doing this.

All activity related to publishing this report (and fixing the bugs mentioned in it) was tracked on https://phabricator.wikimedia.org/T85862 (which has been now made public, it used to be private), which doesn't seem to be linked in the blog post. Two subtasks related to user JS system are https://phabricator.wikimedia.org/T85855 and https://phabricator.wikimedia.org/T85856 , you can read the discussion there.
