Armatura One: Use of Hard-coded Cryptographic Key
CVE-2026-94591 is a high-severity use of hard-coded cryptographic key vulnerability in Armatura One from Armatura, with a CVSS 3.1 base score of 8.4 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, without any action from a user. The record lists version 4.7.2 as the first without the flaw, so updating Armatura One to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.09% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Armatura One to 4.7.2 or a later version.
- Update Armatura One (USA) to 4.6.1 or a later version.
Affected products and versions

How the severity score breaks down
- Attack vector
- LocalThe attacker needs local access or must trick a user into running something.
- Attack complexity
- LowNo special conditions are needed; the attack works reliably.
- Privileges required

Official description
Armatura One stores database and message-broker credentials in an install configuration file, encrypting them with AES-128-CBC when this protection is enabled. The encryption key and initialization vector are fixed values embedded in the software itself and are identical across every installation. An attacker with a copy of the installation package can recover this key and initialization vector, and can then decrypt the stored credentials of any specific installation to which the attacker separately obtains the encrypted configuration file.
