// Description

The Industrial Edge App Publisher contains a vulnerability chain involving improper certificate validation and the rendering of unescaped data from backend responses. These issues can be combined to allow an attacker on the network to impersonate the management server and execute arbitrary code (RCE) on the local machine through Node.js integration. Siemens has released an update for the Industrial Edge App Publisher and recommends to update to the latest version.

CVE ID CVSS Score Severity Description
CVE-2026-78556 7.4 high
CVE-2026-78556. The affected software does not properly validate the server certificate when initiating a TLS connection. This allows an attacker to intercept and relay communication (Man-in-the-Middle attack) and to spoof a trusted entity by interfering in the communication path between the client and the intended server.
CVE-2026-78557 8.3 high
CVE-2026-78557. 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
