CVE-2026-41721: CWE-400: Uncontrolled Resource Consumption in Spring Spring Data Commons
Spring Data Commons contains a vulnerability (CVE-2026-41721) that can cause a Denial of Service (DoS) via uncontrolled resource consumption. This occurs when Spring Data Web Support is enabled and a Controller method uses @ProjectedPayload, allowing an attacker to send a crafted HTTP request that triggers excessive memory allocation. The vulnerability affects multiple versions ranging from 2. 7. 0 through 4. 0. 5. The CVSS score is 5. 9, indicating a medium severity level.
AI Analysis
Technical Summary
CVE-2026-41721 is an uncontrolled resource consumption vulnerability in Spring Data Commons. When Spring Data Web Support is enabled alongside a Controller method annotated with @ProjectedPayload, an attacker can send a specially crafted HTTP request that causes the application to allocate excessive memory, leading to a Denial of Service condition. The affected versions include Spring Data Commons 2.7.0 through 2.7.19, 3.0.0 through 3.0.15, 3.1.0 through 3.1.14, 3.2.0 through 3.2.15, 3.3.0 through 3.3.16, 3.4.0 through 3.4.14, 3.5.0 through 3.5.11, and 4.0.0 through 4.0.5. No official remediation or patch information is provided in the available data.
Potential Impact
An attacker can cause a Denial of Service by triggering uncontrolled memory allocation in affected Spring Data Commons versions when Spring Data Web Support and @ProjectedPayload are used together. This can degrade or crash the application, impacting availability. There is no indication of confidentiality or integrity impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider disabling Spring Data Web Support or avoiding the use of @ProjectedPayload in Controller methods to reduce exposure.
