EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 74% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. In Steeltoe.Discovery.Eureka prior to versions 4.2.0 and 3.4.0, DataCenterInfo.FromJson throws ArgumentException for any name value other than "MyOwn" or "Amazon", despite the Java Eureka specification defining a third valid value: "Netflix". The exception propagates through the entire registry deserialization chain and is swallowed by the periodic cache refresh task, leaving the local service registry permanently empty or stale. Versions 4.2.0 and 3.4.0 patch the issue. If an immediate upgrade is not possible, remove any registrations using unsupported DataCenterInfo.name values from the registry. In mixed Java/Spring and Steeltoe environments, audit for the Netflix data center type before deploying Steeltoe Eureka clients.
