CVE-2026-40989: CWE-674 Uncontrolled Recursion in Spring Spring Cloud Function
CVE-2026-40989 is a medium severity vulnerability in Spring Cloud Function involving uncontrolled recursion in the routing layer. This flaw can cause an out-of-memory (OOM) condition, resulting in denial of service. It does not affect confidentiality but impacts availability due to resource exhaustion. The vulnerability affects specific versions of Spring Cloud Function. No official patch or remediation guidance is currently confirmed.
AI Analysis
Technical Summary
CVE-2026-40989 is a vulnerability classified under CWE-674 (Uncontrolled Recursion) found in Spring Cloud Function. The issue arises from uncontrolled recursion in the routing layer, which can lead to excessive memory consumption and ultimately an out-of-memory error. This results in denial of service by exhausting system resources. The vulnerability affects multiple specific versions of Spring Cloud Function, namely 3.2.0, 4.1.0, 4.2.0, 4.3.0, and 5.0.0. There is no confirmed remediation or patch available as per the provided data.
Potential Impact
The vulnerability does not compromise confidentiality or integrity but can cause denial of service through resource exhaustion (out-of-memory). This can disrupt availability of applications using affected versions of Spring Cloud Function.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider limiting exposure of affected components and monitoring for abnormal resource usage related to recursion in the routing layer.
