Attack Vectors
CVE-2026-24373 is a Critical authentication bypass vulnerability (CVSS 9.8, vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) affecting the WordPress plugin RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login (slug: custom-registration-form-builder-with-submission-manager) in versions <= 6.0.7.1.
Because this issue can be exploited remotely and by unauthenticated attackers, the most common exposure is any public-facing WordPress site running the plugin—especially sites that use it for registration, user login, or payment-related workflows.
Security Weakness
The core weakness is an authentication bypass condition in RegistrationMagic versions up to and including 6.0.7.1. In business terms, this means an attacker may be able to get in without valid credentials, undermining the trust your site places in login and access controls.
This vulnerability is documented by Wordfence and tracked as CVE-2026-24373. If your site uses RegistrationMagic for customer or partner sign-ups, gated content, member portals, or any login-protected experience, the risk is elevated because those workflows rely on reliable identity checks.
Remediation: Update RegistrationMagic to version 6.0.7.2 or a newer patched version per the vendor guidance referenced by Wordfence.
Technical or Business Impacts
With an authentication bypass rated Critical, the expected outcome is loss of control over who can access your WordPress environment and what they can do once inside. Depending on how accounts, roles, and permissions are configured, impacts may include unauthorized access to protected pages, user accounts, administrative functions, or sensitive site data.
From a business-risk standpoint, this can translate into brand damage (defacement or fraudulent content changes), data exposure (customer records, registration details, form submissions), operational disruption (site lockout or downtime), and compliance and legal risk if personal data is accessed or altered. Marketing teams may also face campaign interruption and loss of lead integrity if forms and registration journeys are compromised.
Given the CVSS profile (no privileges required, no user interaction), many organizations treat this class of issue as an emergency patch for any internet-exposed site running the affected plugin versions.
Similar Attacks
Authentication bypass and session-related weaknesses are frequently abused at scale because they can enable immediate unauthorized access without phishing or stolen passwords. Examples of widely reported, real-world cases include:
CISA Advisory AA22-258A: Fortinet FortiOS / FortiProxy authentication bypass (CVE-2022-40684)
