Potential for deserialization of untrusted types in Spring Cloud Stream. Spring Cloud Stream 5.0.0 - 5.0.2 Spring Cloud Stream 4.3.0 - 4.3.3 Spring Cloud Stream 4.2.0 - 4.2.6
AnalysisAI
Spring Cloud Stream versions 5.0.0-5.0.2, 4.3.0-4.3.3, and 4.2.0-4.2.6 expose a deserialization of untrusted types flaw that could allow a network-positioned attacker with high privileges and required user interaction to gain limited read and write access to application data. The CVSS vector (AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N) reflects heavy exploitation constraints, making real-world abuse unlikely without insider-level access and specific preconditions. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold high-privilege credentials (PR:H per CVSS), meaning control over the application layer, its messaging infrastructure, or an administrative account - not an anonymous or low-privileged network position. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Converging signals consistently place this in the low-priority tier. … 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 | Upgrade Spring Cloud Stream to a fixed release as specified in the VMware/Spring security advisory at https://spring.io/security/cve-2026-59306. … Detailed patch versions, workarounds, and compensating controls in full report. |
