### Is CVE-2026-125390 being exploited?

### What does this mean?

A logged-in user with create permission on their own home folder can use the upload queue processing to read files the PHP process can access. That includes the Group-Office config file with database credentials, other users' stored files that bypass folder access controls, and system files.
