Executive Summary

CVE-2026-2328 is a vulnerability in WAGO Device Sphere and WAGO Solution Builder that allows an unauthenticated remote attacker to exploit insufficient input validation through a path traversal attack.

This means the attacker can access backend components beyond their intended scope by manipulating input paths, which bypasses normal security restrictions.

As a result, sensitive information may be exposed even though system integrity and availability are not affected.
