AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N
Consistent with vendor-assigned vector; PR:H and AC:H reflect high-privilege Avro pipeline access and specific sequencing requirements; no availability impact applies.
Primary rating from Vendor (vmware).

Improper caching of the original content type in Spring Cloud Stream Avro. 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
Improper content-type caching in the Avro component of Spring Cloud Stream can produce incorrect content-type metadata on processed messages, creating a low-severity information-disclosure and data-integrity risk. Affected versions span the 4.2.x, 4.3.x, and 5.0.x release trains. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following conditions simultaneously: (1) the target application uses Spring Cloud Stream with the Avro binder component enabled - deployments using JSON, Protobuf, or other serializers are not affected; (2) the attacker must hold high-privilege access (PR:H per CVSS), meaning they must be authenticated with elevated rights over the messaging infrastructure or application configuration; (3) high attack complexity (AC:H) implies specific timing or sequencing conditions must be met; (4) user interaction (UI:R) is required, meaning a legitimate privileged user must take some action to trigger the flawed code path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The overall risk is low. … 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 Cloud Stream to a version outside the affected ranges for each supported train. … Detailed patch versions, workarounds, and compensating controls in full report. |
