Cannot set password for shared links

nc16
#1

Server configuration

Operating system: Ubuntu 18.04 LTS
Web server: Apache 2.4.29
Database: MySQL 5.7.26
PHP version: PHP 7.2.19
Nextcloud version: 16.0.1

Expected behaviour

  • (With “enforce password protection” enabled for shared links) A link is provided after choosing a password for a shared link.
  • (With “enforce password protection” disabled for shared links) A link can be password protected.

Actual behaviour

Nothing happens once a password is entered.

Is this the first time you’ve seen this error?

Yes but never tried this before.

Steps to reproduce

  • (With “enforce password protection” enabled for shared links) Navigate to a gallery/folder -> click share button -> tick “Share link” -> type a password and press Enter -> a loading icon appears briefly, then the password box blanks out and nothing happens.
  • (With “enforce password protection” disabled for shared links) Navigate to a gallery/folder -> click share button -> tick “Share link” -> tick “Password protect” -> type a password and press Enter -> a loading icon appears briefly, then the password box blanks out -> copy the link URL -> paste it in a private browsing window -> can access it without a password.

Details

I discovered this after trying to share a folder for the first time. I had “enforce password protection” enabled for shared links in my admin settings, so when I try to share a link the first thing it asks is to type a password. I cannot get past this stage. It doesn’t matter what I type, it just briefly shows a loading icon then just removes what I’ve typed:

I tried disabling “enforce password protection” and now I can actually share links, but I cannot choose a password. There’s no real indication that the password I try to apply doesn’t take effect, which is a bit of a security issue also. Trying the share links in a private browser shows no password is asked.

Extra Info

  • This was happening with the previous version too (15.x).
  • Nothing is printed to the logs, despite having debug logging enabled in the settings.
  • Nothing relevant seems to be printed to the PHP or Apache logs either.
  • This happens in both Firefox and vanilla Chromium.
