HIGHPre-NVD 8.18.1—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 76% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
