Vendor/Project: jetmonsters
Product: JetFormBuilder — Dynamic Blocks Form Builder

Description

The JetFormBuilder — Dynamic Blocks Form Builder WordPress plugin is affected by a critical privilege escalation vulnerability in all versions up to and including 3.6.2. The flaw arises because the plugin does not verify that a submitted form ID corresponds to a JetFormBuilder form before processing the form schema and executing server-side validation callbacks. This allows unauthenticated attackers to escalate privileges by creating new administrator-level user accounts.

Technical Analysis

CVE-2026-12793 is a critical privilege escalation vulnerability (CWE-269) in the JetFormBuilder — Dynamic Blocks Form Builder WordPress plugin. The vulnerability exists because the plugin fails to validate that a submitted form ID belongs to a legitimate JetFormBuilder form before parsing the referenced post content as a form schema and executing an advanced validation callback on the server side. This improper privilege management enables unauthenticated attackers to create new administrator accounts, effectively gaining full control over the affected WordPress site. The vulnerability affects all versions from 0 up to and including 3.6.2.

Potential Impact

Successful exploitation allows unauthenticated attackers to create new administrator-level user accounts on the affected WordPress site. This results in complete compromise of the site, including confidentiality, integrity, and availability impacts as indicated by the CVSS score of 9.8 (critical).

Mitigation Recommendations

No official patch or fix information is provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the plugin and monitor for suspicious activity. Avoid using affected versions (<=3.6.2) in production environments.
