EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 78% 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).

Nexus Repository 3 contains a Server-Side Request Forgery (SSRF) vulnerability in the email configuration verification feature. A user holding the nexus:settings:update permission could submit arbitrary host and port values to the email test/verification endpoint, causing the server to attempt outbound network connections to internal or otherwise restricted network addresses. Differences in the server's response could be used to infer whether internal hosts and ports are reachable. This issue affects Nexus Repository 3 CE/Pro versions up to and including 3.94.1, and is fixed in version 3.95.0.
