This critical-severity CVE scores 10.0 under NVD CVSS v3. EPSS exploit probability: 4.7%, top 9% 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

SAP NetWeaver AS JAVA (P2P Cluster Communication), versions - 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, allows arbitrary connections from processes because of missing authentication check, that are outside the cluster and even outside the network segment dedicated for the internal cluster communication. As result, an unauthenticated attacker can invoke certain functions that would otherwise be restricted to system administrators only, including access to system administration functions or shutting down the system completely.
