Low risk28th percentile - higher than 28% of all known CVEs
Summary
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.
Risk Assessment
The risk for the organization is critical because an unauthenticated attacker can gain full control over the WordPress site by creating an administrator account. Successful exploitation requires that the site has a public Bricksforge Pro Forms element configured with the User Registration action.
Recommendation
Immediately update the Bricksforge plugin to a version newer than 3.1.8.6 if available. If no update is available, temporarily disable or remove public Bricksforge Pro Forms registration forms until a patch is released.

Versions of Bricksforge <= 3.1.8.4 have a vulnerability that allows unauthorized access to sensitive data.
- CVE-2026-84814Critical
Subscriber privilege escalation vulnerability in Bricksforge versions up to 3.1.8.8, allowing a subscriber to escalate privileges.
- CVE-2026-18030High
The BricksForge WordPress plugin before version 3.1.8.8 does not verify the identity of the requester when processing a password change submitted through one of its form actions. This allows 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 password reset action in update mode; the server-side current-password verification is disabled by default, so the vulnerable state is the default once the action is used.
