Exposures › CVE-2026-12761
miniOrange WordPress plugin allows unauthenticated attackers to bypass authentication and gain admin access via a flawed OTP verification mechanism.
The miniOrange Social Login plugin for WordPress accepts arbitrary email addresses during profile completion and uses a weak, static customer_key combined with a limited OTP space, enabling attackers to crack One-Time Passwords offline and log in as any admin. This authentication bypass grants full administrative control to WordPress sites using the vulnerable plugin, posing a severe risk to organizations relying on WordPress for critical systems or data storage.
Shame score — A critical authentication bypass in a widely used WordPress plugin that allows attackers to gain admin access through a flawed OTP verification process.
The miniOrange Social Login and Register (Discord, Google, Twitter, LinkedIn) plugin for WordPress is vulnerable to authentication bypass leading to account takeover in versions up to and including 7.7.0. This is due to the Profile Completion flow accepting an arbitrary email address via the 'email_field' POST parameter without verifying that the email belongs to the identity returned by the OAuth provider, combined with send_otp_token() returning the SHA-512(customer_key || otp) transaction hash to the client where the OTP space is only 99,000 values (wp_rand(1000, 99999)) and the customer_key is a static option (empty on unregistered installs). This makes it possible for unauthenticated attackers to trigger an OTP email to an arbitrary admin's address, crack the OTP offline from the leaked hash in under a second, and submit the cracked OTP to mo_openid_social_login_validate_otp(), which logs the attacker in as the user whose email was supplied — granting full administrator access.
