Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Network-reachable, unauthenticated SSE endpoint (AV:N/PR:N), but impact is cross-response information disclosure with limited integrity and no availability effect, so lower than the input's 9.8.
Primary rating from Vendor (vmware).

Spring MVC and WebFlux applications are vulnerable to stream corruption when using Server-Sent Events (SSE) with view fragments. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19
Articles & Coverage 1
AnalysisAI
Cross-response information disclosure and stream corruption affects Spring Framework 6.2.0-6.2.19 and 7.0.0-7.0.8 (both MVC and WebFlux) when applications serve Server-Sent Events (SSE) together with view fragments, letting remote attackers corrupt the event stream and potentially bleed data across responses. No public exploit is identified at time of analysis and CISA has not listed the flaw in KEV; EPSS is low at 0.15% (5th percentile). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target application to actively use Server-Sent Events (SSE, text/event-stream responses) rendered together with Spring view fragments - this specific feature combination is the precondition named in the advisory; ordinary Spring apps that do not stream SSE view fragments are not exposed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict and should be weighed rather than taken at face value. … 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 Framework to a fixed release above the affected ranges (i.e., beyond 6.2.19 on the 6.2.x line and beyond 7.0.8 on the 7.0.x line); the exact patched version numbers are not stated in the provided data, so confirm them against the vendor advisory at https://spring.io/security/cve-2026-47890 before pinning - do not assume a specific patch tag. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all applications running Spring Framework 6.2.0-6.2.19 or 7.0.0-7.0.8 that use Server-Sent Events, prioritizing systems handling sensitive customer or financial data. …
