What is CVE-2026-34022?
CVE-2026-34022 is a high-severity vulnerability in Wertheim SafeController Family 65000 Hardware for VAULT ROOMS (Safe Deposit Locker System - Microcontroller), published on 15 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The Wertheim SafeController Family 65000, Controller 65000 - AssemblyVersion 6.11.8130.22319, uses weak custom cryptographic algorithms with hard-coded cryptographic keys to protect communication. An attacker in an adversary-in-the-middle position can decrypt the data traffic. During reassessment, it was possible to break the encryption/decryption routine and decrypt messages without knowledge of the encryption key. It was also possible to gain knowledge about the encryption key by intercepting enough messages.
Weakness: CWE-321
