AI Analysis
Technical Summary
CVE-2026-64664 describes an information exposure vulnerability in Statamic CMS. Authenticated Control Panel users in versions before 5.74.1 and 6.24.0 could use a specific endpoint intended for the user creation wizard to check if an email address corresponds to an existing user, despite lacking permissions to view user details. The endpoint only reveals whether the user exists, not additional user information. This behavior constitutes exposure of sensitive information to unauthorized actors. The vulnerability has been addressed in Statamic versions 5.74.1 and 6.24.0.
Potential Impact
The vulnerability allows authenticated users without user viewing permissions to confirm the existence of user email addresses. While no other user data is exposed, this could aid in user enumeration attacks or targeted phishing. 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 vulnerability is fixed. No other mitigation is indicated by the vendor advisory.
