Security Impact
CVSS: 8.1
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N).
How to Fix CVE-2026-41700
To remediate this vulnerability, upgrade all affected Spring for GraphQL dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

<version>Latest secure release</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.springframework.graphqlHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-41700, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.springframework.graphqlAnalyze the terminal output to locate any version of Spring for GraphQL in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.4), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.springframework.graphql command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
