What to Know

A vulnerability has been identified in Industrial Edge App Publisher (All versions < V1.27.9). The application fails to properly sanitize or escape data received from the backend before rendering it in the user interface. Because the front end is integrated with Node.js, this vulnerability allows for the execution of arbitrary JavaScript, which can be leveraged to achieve remote code execution (RCE) on the victim's machine (NVD)
