Detailsinfo

A vulnerability was found in VentraConnect Social Login, Passkeys and Magic Link & Email OTP Plugin up to 1.4.3. It has been declared as critical. This vulnerability affects the function Generic::normalize_common of the component Spotify OAuth. The manipulation of the argument email with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The Social Login, Passkeys, Magic Link & Email OTP – Passwordless Login by VentraConnect plugin for WordPress is vulnerable to Authentication Bypass via Unverified Provider Email in all versions up to, and including, 1.4.3. This is due to the plugin trusting the unverified email field returned by Spotify's /v1/me endpoint as proof of mailbox ownership — Generic::normalize_common() copies this value into the normalized profile without requiring an email_verified assertion, and User_Links::link_or_login_user() subsequently passes it directly to get_user_by('email', $email) and issues a persistent authentication cookie via wp_set_auth_cookie() without a provider-specific verified-email gate, a local mailbox challenge, or a logged-in approval step. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including Administrators, by supplying a known target email address through a controlled Spotify OAuth flow, gaining full administrative access to the site.

The advisory is available at wordfence.com. This vulnerability was named CVE-2026-18961 since 08/05/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 08/12/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
