Advisories for Composer/Phpmyfaq/Phpmyfaq package

Several public API endpoints return email addresses and non‑public records (e.g. open questions with isVisible=false).

A logged‑in user without the dlattachment right can download FAQ attachments. This is due to a permissive permission check in attachment.php that treats the mere presence of a right key as authorization and a flawed group/user logic expression.

Authenticated non‑admin users can call /api/setup/backup and trigger a configuration backup. The endpoint only checks authentication, not authorization, and returns a link to the generated ZIP.
