Summary
Spring Cloud Function Framework vulnerable to Denial of Service
Full technical description
In Spring Cloud Function framework, versions 4.1.x prior to 4.1.2, 4.0.x prior to 4.0.8 an application is vulnerable to a DOS attack when attempting to compose functions with non-existing functions.
Specifically, an application is vulnerable when all of the following are true:
User is using Spring Cloud Function Web module
Affected Spring Products and Versions Spring Cloud Function Framework 4.1.0 to 4.1.2 4.0.0 to 4.0.8
References https://spring.io/security/cve-2022-22979 https://checkmarx.com/blog/spring-function-cloud-dos-cve-2022-22979-and-unintended-function-invocation/ History 2020-01-16: Initial vulnerability report published.
Impact
The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.
CVE-2024-22271 has a CVSS score of 8.2 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (4.0.8, 4.1.2); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2024-22271? CVE-2024-22271 is a high-severity improper input validation vulnerability in org.springframework.cloud:spring-cloud-function-context (maven), affecting versions >= 4.0.0, < 4.0.8. It is fixed in 4.0.8, 4.1.2. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
- How severe is CVE-2024-22271? CVE-2024-22271 has a CVSS score of 8.2 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of org.springframework.cloud:spring-cloud-function-context are affected by CVE-2024-22271? org.springframework.cloud:spring-cloud-function-context (maven) versions >= 4.0.0, < 4.0.8 is affected.
- Is there a fix for CVE-2024-22271? Yes. CVE-2024-22271 is fixed in 4.0.8, 4.1.2. Upgrade to this version or later.
- Is CVE-2024-22271 exploitable, and should I be worried? Whether CVE-2024-22271 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2024-22271 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
