HIGHPre-NVD 8.38.3—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 80% 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).

OMICRON StationScout before version 3.05 contains a cryptographic timing side-channel vulnerability in the backend authentication mechanism that may allow an unauthenticated attacker to forge valid authentication credentials, bypass authentication and authorization, and impersonate legitimate clients. An attacker can gain full access to the system configuration, allowing modification, reset, or unauthorized alteration of system parameters or injecting network traffic into the connected network.
