Statamic: Account takeover via OAuth email matching without email-verification check
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Packagist | statamic/cms | < 5.74.1 | 5.74.1 |
| Packagist | statamic/cms | >= 6.0.0, < 6.24.0 | 6.24.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
