Security Impact
CVSS: 8.7
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N).
How to Fix CVE-2021-37694
To remediate this vulnerability, upgrade all affected Spring Framework dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install @asyncapi/java-spring-cloud-stream-template@0.7.0Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @asyncapi/java-spring-cloud-stream-templateHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2021-37694, inspect your project dependencies using npm:
npm ls @asyncapi/java-spring-cloud-stream-templateAnalyze the terminal output to locate any version of Spring Framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.0), your application is affected.
Note: The npm ls @asyncapi/java-spring-cloud-stream-template command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Spring Framework, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
