Bricksforge CVE-2026-84814

Q: Which versions of Bricksforge are affected by CVE-2026-84814?

Bricksforge WordPress plugin versions 3.1.8.8 and below contain a critical privilege escalation flaw enabling low-privilege subscriber accounts to gain full administrative access.

Q: How to fix or mitigate CVE-2026-84814?

Within 24 hours, conduct an immediate inventory of all WordPress installations running Bricksforge plugin version 3.1.8.8 or earlier, audit recent admin and subscriber account activity logs for unauthorized privilege changes, and assess the business criticality of Bricksforge functionality. Within 7 days, if Bricksforge features are non-essential, disable and uninstall the plugin entirely; if functionality is business-critical, immediately restrict the Subscriber user role to minimum necessary permissions via WordPress role management or hardening plugins, and enforce multi-factor authentication on all admin and editor accounts. Within 30 days, establish monitoring of Patchstack and vendor advisories for patch availability, test any released patch immediately in staging before production deployment, conduct a comprehensive audit of user roles to enforce least-privilege access, and evaluate alternative plugins for equivalent functionality.

Vulnerability Assessment

Weakness	CWE CWE-266 OWASP Top 10:2025 A06:2025 - Insecure Design ASVS 5.0 V8 - Authorization Privilege assignment review
Exploitation Conditions	Exploitation targets sites running the Bricksforge plugin at version 3.1.8.8 or earlier. The 'Subscriber Privilege Escalation' designation indicates the attacker needs a low-privileged (subscriber) authenticated account - readily obtainable on sites with open registration enabled, but a limiting factor on sites that disable self-registration. The supplied CVSS vector states PR:N/UI:N (no privileges, no user interaction), which conflicts with the subscriber framing and should be confirmed with the vendor; the realistic prerequisite is a logged-in low-tier account plus the plugin being active. No specific non-default configuration beyond having the plugin installed is described.
Impact	The provided CVSS:3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H = 9.8) rates this as network-exploitable with no privileges, but the vulnerability title 'Subscriber Privilege Escalation' indicates an authenticated subscriber-level account is the practical precondition - a tension worth verifying with the vendor, since PR:N conflicts with the subscriber framing. On WordPress sites that allow open user registration, a subscriber account is trivial to obtain, so the effective barrier is low and the privilege-escalation-to-admin outcome (which can lead to full site takeover) means any operator running the plugin should treat this as urgent and patch promptly. However, the analysis rests on a single source (Patchstack) with no EPSS probability, no KEV entry, and no public PoC provided, so exploitation likelihood is currently unquantified. Overall this reads as a genuine high-priority WordPress plugin flaw whose real-world risk hinges on whether the site permits self-registration.
Exploit ScenarioDerived	An attacker registers or uses an existing subscriber account on a WordPress site running Bricksforge <= 3.1.8.8, then sends a crafted request to the plugin's role/capability-handling endpoint that lacks a proper authorization check, promoting their own account to administrator. With admin access they install a malicious plugin or theme to achieve full site compromise. No public PoC was identified at time of analysis.

AnalysisAIv1 – Sep 03, 2026

Privilege escalation in the Bricksforge WordPress plugin (versions <= 3.1.8.8) lets a low-privileged user elevate their account to higher-privileged roles, per a Patchstack advisory. The flaw (CWE-266, Incorrect Privilege Assignment) carries a CVSS of 9.8 with a network/no-auth vector, though the 'Subscriber Privilege Escalation' label implies a logged-in subscriber account is the realistic starting point. No public exploit code, KEV listing, or EPSS score was provided at time of analysis.

RemediationAI

Upgrade Bricksforge to a version newer than 3.1.8.8 (the fixed release number was not stated in the provided data; confirm the exact patched version via the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/bricksforge/vulnerability/wordpress-bricksforge-plugin-3-1-8-8-privilege-escalation-vulnerability and the plugin's changelog before deploying). As interim compensating controls until patched: disable open user self-registration (Settings > General > 'Anyone can register' unchecked) to remove the low-privilege foothold, temporarily deactivate the Bricksforge plugin if the affected form/workflow feature is not essential (trade-off: breaks any forms or automations built with it), and apply a WAF virtual patch or Patchstack protection to block the exploit request. Audit existing user accounts and roles for unauthorized elevation as a detection step.

Technical ContextAI · show details

Bricksforge is a form-builder and workflow/automation add-on plugin for the Bricks visual site builder on WordPress, deployed on sites using that page-builder ecosystem. The root cause is CWE-266 (Incorrect Privilege Assignment): the plugin assigns or grants role/capability changes without correctly enforcing who is authorized to perform them, allowing a lower-tier account to obtain capabilities of a higher role. In WordPress this class of bug typically surfaces in AJAX/REST handlers or form-action logic that update user roles, meta, or capabilities without a proper capability check or nonce validation. The affected CPE is cpe:2.3:a:bricksforge.:bricksforge (note the cosmetic trailing dot in the vendor slug); all versions up to and including 3.1.8.8 are listed as vulnerable.

Subscriber Privilege Escalation in Bricksforge <= 3.1.8.8 versions.

Executive ViewAI

Why It Matters

Bricksforge WordPress plugin versions 3.1.8.8 and below contain a critical privilege escalation flaw enabling low-privilege subscriber accounts to gain full administrative access. Organizations using this plugin face immediate risk of unauthorized site control, data access, and system compromise, with no vendor patch currently available to address the vulnerability. Immediate remediation is required to prevent account takeover and site compromise.

Business Impact: Severe

Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations include disabling the Bricksforge plugin if features are not business-critical. If functionality is required, restrict the Subscriber user role to minimum necessary permissions via WordPress role management or hardening plugins, enforce multi-factor authentication for all privileged accounts, and implement comprehensive logging and alerting for role and permission changes. Conduct weekly audits of admin and editor accounts for unauthorized modifications. While these controls reduce risk, they do not fully eliminate the vulnerability-vendor patch availability is essential for complete remediation.
