Technical details
The plugin does not sandbox its template engine, permitting stored form-editor content to be processed as executable template code. An authenticated administrator can inject server-side template injection (SSTI) payloads in form text blocks that execute with server privileges, enabling arbitrary code execution. The compiled payload executes on each form view, allowing unauthenticated users to retrieve server-side secrets including authentication salts and database credentials.
