Steps to reproduce

  1. Create a folder. In its name, include a % sign.
  2. Next time you navigate to the folder containing that folder, you'll get an infinite spinny loading wheel and the contents of the directory will never appear. nextcloud.log will contain no record of the incident, and the web server will not throw an error.
  3. Navigating on the command line to your userid/files/path/to/dir_which_refuses_to_load, rename the offending folder to something not containing a %. Then occ files:scan userid to set things right.

Expected behaviour

Either % should be refused when (re)naming a directory, or the web interface shouldn't hang when trying to enumerate a directory whose contents contain a directory with a % in the name.

Actual behaviour

Sadness.

Server configuration

Nextcloud 14.0.3 is running on a 12-core Xeon with 16GB RAM. Debian Testing, nginx, PHP 7.2 and 7.3 (I upgraded while troubleshooting this issue), postgresql. My data directory lives on an NTFS drive attached to my router serving as my home SAN. The drive is mounted to my Debian box via automount / CIFS, and then remounted to /var/www/data with bindfs for permissions / ownership sorcery.
