CVE-2026-22740: CWE-400 Uncontrolled Resource Consumption in VMware Spring Framework
CVE-2026-22740 is a medium severity vulnerability in VMware Spring Framework affecting certain versions. It involves uncontrolled resource consumption due to temporary files created by WebFlux server applications processing multipart requests. These temp files, created for parts larger than 10 KB, may not be deleted after request completion, potentially allowing attackers to exhaust disk space. The vulnerability affects specific versions including 5.3.0, 6.1.0, 6.2.0, and 7.0.0. No official patch or remediation guidance is currently available.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-22740) in VMware Spring Framework arises from the WebFlux server application's handling of multipart requests. When processing parts larger than 10 KB, temporary files are created but under certain conditions these files may not be deleted after the request is fully processed. This behavior can lead to uncontrolled resource consumption, specifically disk space exhaustion, categorized under CWE-400. The issue affects multiple specified versions of the Spring Framework. There is no vendor advisory indicating a patch or fix at this time.
Potential Impact
The vulnerability allows an attacker to cause a denial of service condition by consuming available disk space on the server hosting the Spring Framework application. This does not impact confidentiality or integrity but can disrupt availability by exhausting disk resources.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, monitor disk usage and consider implementing application-level controls to limit multipart request sizes or clean up temporary files manually.
