CVE-2026-18030 in BricksForge Plugin
Summary
by MITRE • 08/10/2026
The BricksForge WordPress plugin before 3.1.8.8 does not verify the identity of the requester when processing a password change submitted through one of its form actions, allowing unauthenticated attackers to set an arbitrary password for any user, including administrators, and take over their account.
Exploitation requires the site to have a form using the BricksForge WordPress plugin before 3.1.8.8's password reset action in its update mode. The server-side current-password verification option for that action is disabled by default, so the vulnerable state is the default one once the action is used.

The BricksForge WordPress plugin vulnerability represents a critical authentication bypass flaw that directly undermines user account security within WordPress environments. This issue affects versions prior to 3.1.8.8 and stems from inadequate request validation mechanisms during password change operations. The vulnerability operates at the core of WordPress authentication systems where proper identity verification should occur before any privilege escalation can take place.
The technical implementation flaw resides in the plugin's form processing logic which fails to validate requester credentials when handling password reset requests. Specifically, the plugin's password change action does not perform server-side verification of the current password before allowing a new password to be set. This design decision creates an authentication gap where any unauthenticated attacker can submit a password change request targeting any user account on the system. The vulnerability is particularly dangerous because it operates in its default configuration, meaning no additional misconfiguration or specific setup is required for exploitation to occur.
This weakness enables unauthorized account takeover scenarios with severe operational implications across multiple attack vectors. An attacker can leverage this vulnerability to gain administrative control over WordPress sites by resetting administrator passwords without possessing legitimate credentials. The impact extends beyond simple privilege escalation as it allows full control over website content, user management, plugin configurations, and potentially access to underlying server resources. From an att&ck framework perspective, this vulnerability maps directly to privilege escalation techniques under the credential access category, specifically targeting the modification of account credentials to maintain persistent access.
The default vulnerable state of the plugin configuration creates a particularly concerning threat landscape where any WordPress site using BricksForge before version 3.1.8.8 is inherently exposed to this attack vector without requiring additional reconnaissance or exploitation steps. The vulnerability's persistence stems from the fact that the problematic server-side verification option is disabled by default, making it an automatic target for attackers seeking to compromise WordPress installations. Industry standards such as cwe-287 highlight the importance of proper authentication mechanisms and validate that this flaw constitutes a serious weakness in authentication protocols.
Mitigation strategies must include immediate plugin updates to version 3.1.8.8 or later where the authentication verification has been properly implemented. System administrators should also conduct thorough audits of all WordPress installations to identify potentially vulnerable plugins and ensure that password change actions are properly configured with server-side verification enabled. Additional defensive measures include implementing web application firewalls, monitoring for suspicious authentication requests, and establishing robust account monitoring procedures. The vulnerability underscores the critical importance of proper input validation and authentication mechanisms in web applications, particularly those handling sensitive user credential information.
