Impact

A user was able to get the full data directory path of the Nextcloud server from an API endpoint. By itself this information is not problematic as it can also be guessed for most common setups, but it could speed up other unknown attacks in the future if the information is known.

Patches

It is recommended that the Nextcloud Server is upgraded to 22.2.11 or 23.0.11 or 24.0.6
