DescriptionCVE.org

The Spring Cloud Config Monitor is susceptible to Denial of Service attacks via malicious payloads. Spring Cloud Config 5.0.0 - 5.0.4 Spring Cloud Config 4.3.0 - 4.3.4 Spring Cloud Config 4.0.0 - 4.2.8 Spring Cloud Config 3.1.14 and earlier

AnalysisAI

Denial of Service in Spring Cloud Config's Monitor component allows unauthenticated remote attackers to crash or degrade the configuration server by submitting malicious payloads to the webhook endpoint. Affected versions span the 3.x, 4.x, and 5.x release lines, covering a broad installed base of Spring Boot microservice environments. …

Vulnerability AssessmentAI

Exploitation The spring-cloud-config-monitor dependency must be present and active in the deployment - the Monitor endpoint (/monitor) is not included in a base Spring Cloud Config Server unless this optional module is added. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The vendor-assigned CVSS 5.3 Medium with vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L accurately reflects a remotely exploitable, zero-prerequisite DoS with limited (partial) availability impact and no confidentiality or integrity exposure. … 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 Consult and apply the patched release identified in the VMware/Spring security advisory at https://spring.io/security/cve-2026-59315 - exact fix versions were not included in the available input data and should be confirmed directly from that source before upgrading. … Detailed patch versions, workarounds, and compensating controls in full report.
