CVE-2026-90456
CRITICAL 9.2An example environment-configuration file for a bundled inventory-management component ships with a fixed, publicly-known administrative password. A deployment that copies this example file into active configuration without running the setup routine that regenerates credentials will expose that component's administrative interface to anyone aware of the default value.
Severe if exploited (CVSS 9.2), but no known exploitation and low modeled probability. Patch on a normal cadence.
