CVE-2025-40805 is a critical authorization bypass vulnerability in Siemens Industrial Edge Device Kit affecting arm64 and x86-64 releases, including versions V1.5 through V1.23, V1.24 prior to 1.24.2, and V1.25 prior to 1.25.1. The flaw arises because affected devices do not properly enforce user authentication on specific API endpoints. As a result, an unauthenticated remote attacker who knows the identity of a legitimate user can circumvent authentication checks and impersonate that user when interacting with the vulnerable API functionality. The issue is classified as CWE-639 and has been assigned CVSS v3.1 10.0 with network reachability, low attack complexity, no privileges required, no user interaction, and changed scope.
