EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.1 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 86% 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 user able to connect to Agent 2 can inject an Oracle TNS connection string via the 'service' parameter. This can lead to Agent 2 connecting to an attacker-controlled server and leaking Oracle database credentials if they are saved in a named session.
