Thanks for raising @archinfoto,
Looks to be due to the changes made in #5601 which were part of BookStack v25.02.3.
Probably won't affect many instances where php & the web-server run as the same user, but will be one to patch soon as there's also going to be many instances with a multi-user setup like the one here. Will create a new patch release milestone and assign this to it.

Think we'll need to perform the folder creation manually so we have control over the directory permissions (as we have done for file creation).

Hello,

I am indeed affected by this bug on a fresh install at v25.02.4. Thank you for your quick handling of this issue!

Just as a side note, this probably affects many deployments using php-fpm with a pool dedicated to the application, which is usually considered a good practice.
