- Fix
5.74.1- Upgrade statamic/cms to this version or later
Description
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.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-287: Improper Authentication

How to prevent it
- Architecture and Design: Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
CWE-290: Authentication Bypass by Spoofing
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
