Roxnor Wp Social Login and Register Social Counter Improper Authentication Vulnerability

CVSS: 8.1, high high CVSS v3.1
EPSS, next 30 days: 0.4% higher than 38.2% of scored CVEs
Exploitation: No public evidence
Published: 31 Oct 2026yesterday

Description

The Wp Social Login and Register Social Counter plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 3.2.2. This is due to the social login REST callback registered at `/wp-json/wslu-social-login/type/{provider}/` with `permission_callback => __return_true` locating an existing WordPress account solely by the email string returned from the OAuth provider and calling `wp_set_auth_cookie()` without a password check, while the only verification guard (`!empty($getProfile->emailVerified)` in `inc/admin-create-user.php`) is a no-op for the bundled Hybridauth Facebook and Twitter adapters, both of which assign the raw email string rather than a boolean verified flag to `emailVerified`. This makes it possible for unauthenticated attackers to obtain a fully authenticated session as any existing WordPress user, including Administrators, whose registered email address can be presented through a configured Facebook or Twitter login on the target site. Exploitation requires only that the attacker control an OAuth account whose provider-returned email matches the target account's registered WordPress email address; no local credentials, nonce, or prior foothold is needed.
