Backdrop CMS 1.33.3 removes a duplicate #process callback from the password element and corrects faulty permission checks for accessing site reports.

Why it matters: Fixing the duplicate callback prevents erratic behavior in password handling; correcting the permission check blocks unauthorized access to sensitive site‑report data—critical for all deployments using these features.
