CVE-2022-22979
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn Spring Cloud Function versions prior to 3.2.6, it is possible for a user who directly interacts with framework provided lookup functionality to cause a denial-of-service condition due to the caching issue in the Function Catalog component of the framework.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA denial-of-service vulnerability exists in Spring Cloud Function's Function Catalog component where the caching mechanism can be exploited via the lookup functionality. A user directly interacting with this functionality can trigger excessive caching, leading to resource exhaustion and service unavailability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Spring Cloud Function installationCheck project dependencies (Maven pom.xml, Gradle build.gradle) or application classpath for 'spring-cloud-function' jar presenceAffected if Spring Cloud Function dependency is present in the project
-
Determine installed Spring Cloud Function versionReview the resolved version of spring-cloud-function in build artifacts, dependency tree (mvn dependency:tree or gradle dependencies), or check the jar manifestAffected if Version is lower than 3.2.6 (e.g., 3.2.5, 3.2.0, etc.)
-
Check if function routing/lookup is enabledInspect application.properties or application.yml for 'spring.cloud.function.definition' or 'spring.cloud.function.routing.enabled' configuration propertiesAffected if Function routing or lookup via FunctionCatalog is explicitly defined or auto-configured
-
Verify caching configuration for function lookupSearch configuration files for caching-related properties affecting FunctionCatalog, such as spring.cloud.function.caching or custom cache settingsAffected if Caching is enabled for function lookup operations (default behavior exposes the vulnerability)
-
Confirm exposure of lookup endpointReview if the application exposes HTTP endpoints that route to function lookup (via spring.cloud.function.web.routing.enabled or similar)Affected if HTTP routing to functions is enabled, allowing direct interaction with the lookup functionality
The environment is affected if Spring Cloud Function version is below 3.2.6 AND the function routing/lookup feature is enabled, allowing attackers to trigger excessive caching through the FunctionCatalog component.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.2.6
Upgrade Spring Cloud Function to version 3.2.6 or later to resolve the caching issue in the Function Catalog component.
Spring Cloud Function 3.2.6
- 1. Identify the current Spring Cloud Function version in use by checking project dependencies (e.g., pom.xml, build.gradle)
- 2. Update the Spring Cloud Function dependency to version 3.2.6 or later
- 3. For Maven projects, update the dependency in pom.xml: change version to 3.2.6
- 4. For Gradle projects, update the dependency in build.gradle: change version to '3.2.6'
- 5. Rebuild and test the application to ensure functionality remains intact
- 6. Deploy the updated application to production environments
