How to Fix CVE-2024-31033

To remediate this vulnerability, upgrade all affected Withdrawn dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.jsonwebtoken:jjwt-impl fixed: Latest secure release 
<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt-impl</artifactId>
    <version>Latest secure release</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=io.jsonwebtoken

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-31033, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jsonwebtoken

Analyze the terminal output to locate any version of Withdrawn in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jsonwebtoken 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.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-327: Use of a Broken or Risky Cryptographic Algorithm, where the product uses a broken or risky cryptographic algorithm or protocol. In Withdrawn, software state validation or input boundaries are circumvented during processing.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.

Source Advisory Statement

## Withdrawn Advisory This advisory has been withdrawn because it has been found to be disputed. Please see the issue [here](https://github.com/jwtk/jjwt/issues/930#issuecomment-2032699358) for more information. ## Original Description JJWT (aka Java JWT) through 0.12.5 ignores certain characters and thus a user might falsely conclude that they have a strong key. The impacted code is the setSigningKey() method within the DefaultJwtParser class and the signWith() method within the DefaultJwtBuilder class.
