AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
UDP is connectionless and the description explicitly states unauthenticated access, so PR:N overrides the official PR:L; C/I/A:L reflects SSRF-class impact.

An unauthenticated remote attacker who can send a single UDP packet to a Spring Integration UDP inbound adapter can cause the server to emit an outbound UDP datagram to an arbitrary internal or external host and port of the attacker's choosing. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12 Spring Integration 5.5.21 and earlier
AnalysisAI
Spring Integration's UDP inbound adapter can be abused by unauthenticated remote attackers to coerce the server into emitting outbound UDP datagrams to arbitrary hosts and ports - a classic UDP Server-Side Request Forgery (SSRF). Affected versions span the entire supported line from 5.5.x through 7.1.0, covering a wide range of enterprise Java deployments. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target application has a Spring Integration UDP inbound channel adapter configured and that its listening port is reachable from the attacker over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The official CVSS score of 6.3 (Medium) carries a notable discrepancy: the vector specifies PR:L (low privileges required), yet the description explicitly states 'unauthenticated remote attacker.' UDP is a connectionless, stateless protocol where no authentication handshake occurs, making PR:N the more accurate metric - this warrants verification with the vendor. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary remediation is to upgrade Spring Integration to a fixed version - consult the vendor advisory at https://spring.io/security/cve-2026-47861 for the exact patched releases, as no specific fix version is confirmed in the available intelligence (patch available per vendor advisory, exact version not independently verified). … Detailed patch versions, workarounds, and compensating controls in full report. |
