Technical Summary
CVE-2026-64664 is an information exposure vulnerability in Statamic CMS affecting versions before 5.74.1 and 6.24.0. An authenticated user with Control Panel access can use a specific endpoint intended for the user creation wizard to determine if a given email address belongs to an existing user. This occurs despite the user lacking permission to view user details. The endpoint only discloses the existence of the user account associated with the email and does not expose other user information. The vulnerability is resolved in Statamic CMS versions 5.74.1 and 6.24.0.
Potential Impact
The vulnerability allows an authenticated Control Panel user to confirm whether an email address is registered in the system without having explicit permission to view user data. This could aid in user enumeration attacks but does not disclose sensitive user details beyond existence. There is no impact on data integrity or availability.
Mitigation Recommendations
Upgrade Statamic CMS to version 5.74.1 or later, or 6.24.0 or later, where this issue is fixed. No other mitigation is required as the vulnerability is resolved in these versions.
