Description

There was a missing permission-check in the shares feature (the shr global-option).

When a share is created for just one file inside a folder, it was possible to access the other files inside that folder by guessing the filenames.

It was not possible to descend into subdirectories in this manner; only the sibling files were accessible.

This issue did not affect filekeys or dirkeys.
