CVE-2026-40990
Description
A flaw was found in Spring Cloud Function. A local attacker with low privileges could exploit this vulnerability by repeatedly adding functions to the Function Registry, leading to an Out Of Memory (OOM) error. This resource exhaustion can cause a Denial of Service (DoS) for the affected application.
Statement
Red Hat's versions of spring-cloud-function shipped as a transitive dependency in EAP XP predate the affected version range and are not impacted by this vulnerability.
Mitigation
No mitigation is required. The shipped versions do not contain the vulnerable code.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
