Summary

Statamic: Account takeover via OAuth email matching without email-verification check

Details

Impact

When OAuth login is enabled with a provider that does not guarantee verified email addresses, an unauthenticated attacker could sign in as an existing user — potentially including a super admin — without their password. Exploitation requires OAuth to be explicitly enabled with such a provider.

Patches

Fixed in 5.74.1 and 6.24.0.

Workarounds

Only enable OAuth with providers that guarantee verified email addresses, or disable OAuth login.

Severity

8.1 (High)

CVE-2026-64665 (GCVE-0-2026-64665)

Vulnerability from cvelistv5 – Published: 2026-08-06 19:25 – Updated: 2026-08-07 17:09

Title

Statamic: Account takeover via OAuth email matching without email-verification check

Summary

Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.1 and 6.24.0, when OAuth login was enabled with a provider that does not guarantee verified email addresses, an unauthenticated attacker could sign in as an existing user, potentially including a super admin, without knowing that user's password, because the application matched OAuth identities to accounts by email address alone. Exploitation requires OAuth to be explicitly enabled with such a provider. This issue is fixed in versions 5.74.1 and 6.24.0.

Severity

8.1 (High)
