Impact
Statamic CMS exposes email addresses of control panel users through the user fieldtype’s data endpoint even to those who lack the "view users" permission, resulting in privacy violations. The flaw is an access‑control weakness (CWE-862) that allows malicious users to retrieve sensitive information that should be protected.
Affected Systems
All Statamic CMS installations running a version earlier than 5.73.11 or 6.4.0 are vulnerable. Upgrading to 5.73.11 or 6.4.0 eliminates the missing authorization check and resolves the issue.
Risk and Exploitability
The CVSS score of 6.5 indicates a Medium severity, while the EPSS score of <1% suggests the likelihood of exploitation is low. The vulnerability is not listed in CISA KEV. Based on the description, it is inferred that attackers could exploit the flaw by sending requests to the API endpoint from any network position that can reach the control panel, provided they are not authenticated with the requisite permission.
