Privilege escalation in Jetmonsters Jetformbuilder — Dynamic Blocks Form Builder
CVE-2026-12793
The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.6.2. This is due to the plugin not validating that a submitted form ID belongs to a JetFormBuilder form before parsing the referenced post's content as form schema and executing an Advanced Validation server-side callback. This makes it possible for unauthenticated attackers to create a new administrator-level user account.
