Description · from the CVE record

Snipe-IT before 8.6.3 contains an authentication bypass in GoogleAuthController::handleGoogleCallback, which logs in the user whose username matches the Google account email without enforcing the activated flag. Deactivated users with email-shaped usernames and still-live Google identities can sign in via Google SSO and regain sessions at their original permission level, including admin.
