Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Craft CMS versions 4.0.0-RC1 up to (but not including) 4.18.1, and 5.0.0-RC1 up to (but not including) 5.10.3, are affected. A control panel user who has only the accessCp permission, and no viewUsers permission, can send a request to the charts endpoint that returns aggregate user registration counts over a chosen time period, either site-wide or for a given user group, because the action lacks the viewUsers permission check. No personal data such as names, emails, or passwords is exposed, only counts and timestamps. The fix is to upgrade to Craft CMS 4.18.1 or 5.10.3.
