Description
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
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-78557 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
