Found this as part of testing J 3.9 Privacy Tools Suite, with a complete, fresh install from https://developer.joomla.org/privacy-pack/. Tried uploading an image via Content -> Media -> Upload. After I selected an image and clicked on the "Upload" button, Joomla returned a message "Fatal error: Class 'Joomla\CMS\Filesystem\JFilterInput' not found in /home3/nimda/public_html/dev/20180728_pbf/libraries/src/Filesystem/File.php on line 543" on an otherwise blank page.

Related PR but for J4 https://github.com/joomla/joomla-cms/pull/21174

I faced the same issue, applied the changes of the PR you're mentioning, now it works as expected.

[bayareajenn]

I applied #21174 in 3.9 and it tested successfully. If there's a separate PR for 3.9, let me know so I can update it. OR, if you want all of us to test #21174 and mark it successful, let us know so everyone else that posted in here can test also.

Done @wojsmol.

@jamgit , @ernienet and @wjlorente will you please go apply the patch with the patchtester 2.0.1 (stable) from https://github.com/joomla-extensions/patchtester/releases (install it via the extension manager) and apply the patch for #21314. Then test to see if you can add media.

Then go to https://issues.joomla.org/tracker/joomla-cms/21314 and login and report whether it tested successfully or not (click the Test this button to do this).
