EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.9%, top 42% 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).

A command Injection vulnerability exists in the WireGuard client configuration of Archer MR600 v5 due to improper neutralization of user-controlled input within the web management interface. An authenticated attacker with administrative privileges may be able to execute arbitrary commands when applying configuration changes.Successful exploitation may result in a full compromise of confidentiality, integrity, and availability of the affected device.
