What is the CVSS score of EUVD-2026-45123?

EUVD-2026-45123 has a CVSS 3.1 base score of 9.8 (Critical). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. EPSS exploitation probability: 0.4%.

How to fix or mitigate EUVD-2026-45123?

Within 24 hours: Identify all WordPress installations running Bricksforge version 3.1.8.6 or earlier and immediately disable the Pro Forms User Registration feature or deactivate the entire plugin. Within 7 days: Audit all administrator accounts created in the past 90 days to identify and remove any unauthorized accounts; reset passwords for all existing administrator accounts; and implement Web Application Firewall rules to block requests to the vulnerable registration endpoint. Within 30 days: Continuously monitor Bricksforge's official security advisories for a vendor patch; if no patch is released, evaluate and implement an alternative form-building plugin that meets your security requirements; and consider permanent removal of Bricksforge from your WordPress environment.

Vulnerability Assessment

Weakness	CWE CWE-269 OWASP Top 10:2025 A06:2025 - Insecure Design ASVS 5.0 V8 - Authorization Least privilege enforcement MITRE ATT&CK 1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. Sign in to read
Exploitation Conditions	Exploitation requires that the target site has a publicly accessible Bricksforge Pro Forms element configured with the User Registration action - this specific feature/configuration is the mandatory precondition and sites without such a form are not exploitable despite running a vulnerable version. Given that prerequisite, no authentication, user interaction, or special client state is needed: an unauthenticated remote attacker submits a single crafted request manipulating the fieldIds parameter. The limiting factor is therefore purely the presence and public exposure of a registration-enabled Pro Forms element, not any privilege or platform requirement.
Impact	This is a genuine high priority, not an inflated CVSS. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/C:H/I:H/A:H, 9.8) is internally consistent: fully remote, no authentication, no user interaction, and full site compromise via administrator takeover. The signals are unusually clean and mutually reinforcing - network reachable, low complexity, and total control of the target WordPress instance once an admin account is created. EPSS and CISA KEV data were not supplied in the input, so exploitation-probability and active-exploitation status are UNKNOWN rather than low - absence of data is not evidence of low risk. No POC was provided. The one meaningful limiting factor that does NOT appear in the CVSS score is a deployment prerequisite: the site must have a publicly accessible Pro Forms element configured with the User Registration action, so not every installation is exploitable even though every version is vulnerable.
Exploit ScenarioDerived	An attacker locates a WordPress site running Bricksforge with a public Pro Forms registration form, then submits a crafted registration request that adds a role/capabilities field ID to the fieldIds parameter and sets its value to administrator. The server accepts the manipulated whitelist and provisions a new administrator account, giving the unauthenticated attacker full control of the site. No public POC is referenced, but the low attack complexity means weaponization would be straightforward.

AnalysisAIv1 – Jul 17, 2026

Unauthenticated privilege escalation in the Bricksforge WordPress plugin (versions ≤ 3.1.8.6) lets remote attackers create a new administrator account by abusing the Pro Forms User Registration action. The plugin fails to validate the fieldIds parameter, so attacker-supplied field IDs are injected into the trusted form-field whitelist, enabling mass-assignment of a privileged role. No public exploit has been identified at time of analysis, but the flaw is trivially exploitable (CVSS 9.8) on any site exposing a Pro Forms registration element.

RemediationAI

Upgrade Bricksforge to a fixed release above 3.1.8.6 as published in the vendor changelog (https://bricksforge.io/version-changelog/); the input does not specify an exact patched version number, so treat this as 'Patch available per vendor advisory' and confirm the fixed build against the changelog before deploying. As an immediate compensating control until patched, unpublish or remove any public Bricksforge Pro Forms element that uses the User Registration action - this fully closes the attack surface but disables self-service registration on affected forms. Where registration must remain available, restrict access to those form endpoints (for example gate the page behind authentication or IP allow-listing) and audit existing WordPress users for unexpected administrator accounts created recently, since exploitation results in a rogue admin. Review the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/d0538778-5ba4-4bec-a89d-ef90a9ba8375) for detection guidance.

Technical ContextAI · show details

Bricksforge is a commercial add-on for the Bricks visual site builder on WordPress, providing 'Pro Forms' - advanced form elements including a User Registration action that maps submitted form fields to WordPress user meta and account properties. The root cause is CWE-269 (Improper Privilege Management): the registration handler trusts a client-supplied fieldIds parameter to determine which fields are permitted, effectively letting the attacker extend the server-side allowlist. Because WordPress user creation maps arbitrary meta/role fields, an attacker can add the wp_capabilities / role field to the whitelist and set it to 'administrator' during self-registration - a classic mass-assignment via broken authorization. The affected component is identified by CPE cpe:2.3:a:bricksforge:bricksforge:*:*:*:*:*:*:*:* covering all versions through 3.1.8.6.

DescriptionCVE.org

The Bricksforge plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.1.8.6. This is due to improper validation of the fieldIds parameter in the Pro Forms registration action, which allows attacker-supplied field IDs to be added to the trusted form-field whitelist. This makes it possible for unauthenticated attackers to register a new administrator account by submitting a crafted request to a publicly accessible Bricksforge Pro Forms registration form. Successful exploitation requires that the site has a public Bricksforge Pro Forms element configured with the User Registration action.

Executive ViewAI

Why It Matters

The Bricksforge WordPress plugin (versions 3.1.8.6 and below) allows unauthenticated remote attackers to create administrator accounts on affected websites, providing complete unauthorized access. This vulnerability poses an immediate and severe risk to any organization running WordPress sites with this plugin installed. Attackers could steal sensitive data, inject malicious code, or disrupt operations across affected web properties.

Business Impact: Severe

Compensating Controls

Immediately disable Pro Forms User Registration through plugin settings or deactivate the plugin entirely. Implement Web Application Firewall rules to block malicious registration requests. Restrict access to registration forms using IP whitelisting or geofencing. Enable real-time alerts for administrator account creation. Implement mandatory two-factor authentication for all WordPress administrators. Switch to manual user account provisioning through the WordPress admin panel.
