In Micrometer, it is possible for a user to provide specially crafted gRPC requests that may cause a denial-of-service (DoS) condition. Affected versions: Micrometer 1.16.0 through 1.16.5; 1.15.0 through 1.15.11.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-40983) in Spring Micrometer involves uncontrolled resource consumption (CWE-400) triggered by maliciously crafted gRPC requests. Affected versions include 1.15.0 through 1.15.11 and 1.16.0 through 1.16.5. The flaw can cause a denial-of-service condition by exhausting resources. The CVSS 3.1 base score is 7.5, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to availability. No patch or vendor advisory detailing remediation is currently available.
Potential Impact
Successful exploitation results in denial-of-service by exhausting system resources when processing crafted gRPC requests. There is no impact on confidentiality or integrity reported. This can disrupt availability of applications using affected Micrometer versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting exposure of gRPC endpoints and applying network-level protections to mitigate potential DoS attempts. Monitor official Spring project communications for updates.
