Exploitation Conditions

Exploitation requires that the target WordPress site has the RegistrationMagic plugin installed and active in a version at or below 6.0.9.8. The CVSS AC:H metric indicates that some specific condition beyond plugin presence must be met - likely a particular plugin configuration, an enabled sub-feature, or a timing/state dependency - though the available description does not enumerate the exact prerequisite. The CVSS PR:N metric confirms no WordPress credentials or authenticated session are required. UI:N means no victim interaction is needed. What limits exploitation is the AC:H complexity requirement, the absence of any known public exploit code, and the necessity that the target site runs this specific plugin version; WordPress sites not running RegistrationMagic are entirely unaffected.

Impact

The CVSS 3.1 base score of 7.4 (High) is driven primarily by the dual C:H/I:H impact and PR:N (unauthenticated) access, partially offset by AC:H which signals that exploitation is not trivially repeatable against arbitrary targets. The AC:H metric is the critical moderating factor: it implies a specific race condition, timing requirement, or non-default configuration state that must be present for the bypass to succeed, meaningfully reducing the automatable exploitation risk compared to an AC:L equivalent. No EPSS score was provided in the input data, so probabilistic exploitation likelihood cannot be quantified independently. The vulnerability is not listed in the CISA KEV catalog and no public proof-of-concept exploit code has been identified, suggesting opportunistic mass exploitation is not currently occurring. However, WordPress plugin authentication bypasses are a highly targeted class - once a working technique is documented in a Patchstack advisory, weaponization by threat actors targeting WordPress installations typically follows quickly. The C:H and I:H impact ratings indicate that a successful exploit could expose sensitive registrant PII and allow unauthorized creation, modification, or deletion of form submissions or user accounts.

Exploit ScenarioDerived

An unauthenticated remote attacker identifies a WordPress site running RegistrationMagic <= 6.0.9.8 and, under the specific conditions required by AC:H, sends a crafted HTTP request that invokes an alternate authentication path - such as a direct AJAX endpoint or REST route lacking proper capability checks - thereby bypassing the plugin's authentication gate. With authentication bypassed, the attacker can read sensitive registration submissions (C:H) or manipulate form data, user records, or plugin configuration (I:H) without ever possessing valid WordPress credentials. No public proof-of-concept has been identified, but the Patchstack disclosure provides sufficient technical context for capable threat actors to develop working exploits.

AnalysisAIv1 – Aug 31, 2026

Broken authentication in RegistrationMagic WordPress plugin versions up to and including 6.0.9.8 allows unauthenticated network attackers to bypass authentication controls via an alternate path or channel, achieving high confidentiality and integrity impact without any credentials or user interaction. Classified under CWE-288, the flaw enables unauthorized access to registration and submission management functionality that should be gated behind authentication. No public exploit code or CISA KEV listing has been identified at time of analysis, though the CVSS High severity and dual C:H/I:H impact classify this as a priority remediation for any WordPress deployment running the affected plugin.

RemediationAI

Update the RegistrationMagic plugin to the version immediately following 6.0.9.8 as released by Metagauss; the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/custom-registration-form-builder-with-submission-manager/vulnerability/wordpress-registrationmagic-plugin-6-0-9-8-broken-authentication-vulnerability confirms a patched version is available, though the exact fixed version number is not specified in the available input data and should be verified directly in the WordPress plugin changelog or Patchstack entry before applying. As an interim compensating control, administrators should restrict access to WordPress admin and AJAX endpoints (wp-admin/, wp-login.php, admin-ajax.php) to trusted IP ranges via firewall or web server ACL rules, which reduces the network-accessible attack surface given the AV:N vector - note this may break legitimate front-end form functionality for users outside those ranges. Additionally, enabling a Web Application Firewall (WAF) rule set targeting WordPress authentication bypass patterns (available in plugins such as Wordfence or via Patchstack's Firewall) can provide virtual patching until the official update is applied.

Technical ContextAI · show details

RegistrationMagic is a WordPress plugin developed by Metagauss (CPE: cpe:2.3:a:metagauss:registrationmagic:*:*:*:*:*:*:*:*) providing custom registration form building and submission management capabilities for WordPress sites. The root cause is CWE-288 - Authentication Bypass Using an Alternate Path or Channel - meaning the plugin exposes one or more code paths that allow authentication-sensitive operations to be reached without completing the intended authentication flow. This is distinct from credential brute-forcing; rather, an attacker sidesteps the authentication mechanism entirely, likely through a direct endpoint invocation, parameter manipulation, or a missing capability check on an AJAX handler or REST API route - patterns common in WordPress plugin authentication bypass vulnerabilities. The CVSS AC:H metric indicates exploitation requires some specific condition or confluence of circumstances beyond a simple unauthenticated HTTP request.

Unauthenticated Broken Authentication in RegistrationMagic <= 6.0.9.8 versions.

Executive ViewAI

Why It Matters

The RegistrationMagic WordPress plugin (versions through 6.0.9.8) contains an authentication bypass that exposes registration and submission data to unauthorized access without requiring valid credentials. Any WordPress site using this plugin is vulnerable to data exfiltration and unauthorized modification of user registrations and submissions, creating significant compliance and operational risk.

Business Impact: Severe
Compensating Controls

Until vendor patch is available: Restrict network access to WordPress admin URLs and registration endpoints using WAF rules or IP allowlists; disable plugin functionality via access controls if removal is not immediately feasible; implement real-time monitoring and alerting on registration and submission data access patterns; audit all registration and submission records for unauthorized modifications from the plugin release date forward.
