Steps to reproduce the issue

Create article with contents from attached UTF-8 ddos.txt
Try to edit and save it.
Try different PHP max_execution_time from 10 to 60.

Expected result

Fast saving.

Actual result

White screen with max execution time reached.

System information (as much as possible)

Joomla 3.7.0, JCE Editor Free.

Additional comments

  1. The last executed script is always libraries/vendor/joomla/string/src/phputf8/mbstring/core.php. Lines 41 or 94.
    The caller is libraries/joomla/filter/input.php.

  2. Restoring the 'libraries/joomla/filter/input.php', 'libraries/joomla/filter/output.php' to version < 3.7.0 fixes the issue.

That file hasn't changed in 3 years, restoring that file could not "fix" anything.

I confirm the issue, IHAC reporting the same. I was not able to reproduce yet but I believe this is tinymce specific. Initially the user reported that html formatting was not visible in tinymce (just plain text), to workaround the situation I moved the user specific usergroup to "set0" in the tinymce plug-in. The user is part of a sub-set of the Managers with less less priv (mostly restricted to Users, Articles, Categories, Modules and 1-2 core components + one well ranked 3rd party component).
But he is still hitting the time out in libraries/vendor/joomla/string/src/phputf8/mbstring/core.php on line 94
Was working like a charm in 3.6.5. Average articles in French are about 300 characters, so probably not "size" related.

Brian, my manual change was just about the template names (my bad, I should not have created the templates with such naming), otherwise the file is unmodified. I'm suspecting the user to enter a strange sequence of characters coming along with a cut&paste likely from word. If I can access to the .doc I'll try to nailed down the sequence and post again.
