EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 11.7%, top 4% 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).

An issue was discovered in SmartBear ReadyAPI SoapUI Pro 3.2.5. Due to unsafe use of an Java RMI based protocol in an unsafe configuration, an attacker can inject malicious serialized objects into the communication, resulting in remote code execution in the context of a client-side Network Licensing Protocol component.
