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.

Is GHSA-93qh-5269-9wcf in any of your client repos?

Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected statamic/cms, and gives you the command that fixes it.
