CVE-2026-18961: CWE-287 Improper Authentication in fahdaslam Social Login, Passkeys, Magic Link & Email OTP – Passwordless Login by VentraConnect
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.

Technical Summary
CVE-2026-18961 is an authentication bypass vulnerability (CWE-287) in the Social Login, Passkeys, Magic Link & Email OTP – Passwordless Login plugin by VentraConnect for WordPress. The plugin improperly trusts the unverified email field returned by Spotify's /v1/me endpoint without requiring an email_verified assertion. The function Generic::normalize_common() copies this unverified email into the normalized profile, and User_Links::link_or_login_user() uses it to retrieve the user by email and issue a persistent authentication cookie without additional verification steps. This allows unauthenticated attackers to log in as any existing WordPress user, including administrators, by supplying a known email address through a controlled Spotify OAuth flow, resulting in full administrative site access.
Potential Impact
Successful exploitation allows unauthenticated attackers to bypass authentication and gain full administrative access to the WordPress site. This compromises confidentiality, integrity, and availability of the affected system, enabling complete control over the site and its data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid using the affected plugin versions or disable the plugin to prevent exploitation.
