CVE-2026-64665 — Vulnerability in statamic/cms — CVE Details

HIGH

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

Published August 6, 2026Updated August 6, 2026Source: osv

Summary

### 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.
