ROS# CVE-2026-41551

Q: What is the CVSS score of CVE-2026-41551?

CVE-2026-41551 has a CVSS 4.0 base score of 9.3 (Critical). CVSS vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X. EPSS exploitation probability: 0.0%.

Q: How to fix or mitigate CVE-2026-41551?

Within 24 hours: Identify all systems running Siemens ROS# and document current versions in use; isolate affected systems from network access if V2.2.2 or later cannot be deployed immediately. Within 7 days: Apply mandatory upgrade to Siemens ROS# V2.2.2 or later across all affected deployments; validate patched versions in non-production environments before production rollout. Within 30 days: Complete production deployment of patched versions; conduct file-access audits on systems that ran vulnerable versions to detect potential unauthorized data exfiltration.

CRITICAL 9.1

DescriptionNVD

A vulnerability has been identified in ROS

(All versions < V2.2.2). Affected versions contain a path traversal vulnerability because user input is not properly sanitized.

This could allow a remote attacker to access arbitrary files on the device.

AnalysisAI

Remote path traversal in Siemens ROS# versions prior to V2.2.2 enables unauthenticated attackers to read arbitrary files from affected systems due to insufficient input sanitization. The vulnerability affects the ROS# library, a C# .NET implementation for Robot Operating System communication, with CVSS 9.3 critical severity. …
