Summary
Siemens is currently assessing the impact of Node2Shell (CVE-2026-111497) on Industrial Edge. Please check your Industrial Edge Management (IEM) setup: – No Management Applications installed: No action is required. Although the affected Brotli library is included in the IEM software stack, the affected functionality is not used or exposed. The same applies to IEDK. – Management Applications installed: Follow the specific mitigations until a fix is available. – Device Applications installed: Follow the specific mitigations until a fix is available. For Siemens-managed services, Industrial Edge Hub and Industrial Edge Management Cloud, appropriate Firewall/WAF protection has already been implemented. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fixes and recommends specific mitigations for products where fixes are not or not yet available.

Vulnerabilities
CVE-2026-111497
A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream. Users need to update any Brotli libraries or binaries between 1.0.3 through 1.2.0 to the latest available version: 1.0.10 or 1.1.1 or 1.2.1.
