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=org.typelevel

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-21653, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.typelevel

Analyze the terminal output to locate any version of Jawn parser 0.25 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.typelevel 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Jawn parser 0.25, 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

### Impact Extenders of the `org.typelevel.jawn.SimpleFacade` and `org.typelevel.jawn.MutableFacade` who don't override `objectContext()` are vulnerable to a hash collision attack. Most applications do not implement these traits directly, but inherit from a library: Affected implementations include: * `org.http4s` :: `http4s-play-json` * `org.typelevel :: jawn-ast` (< 0.8.0) * `org.typelevel :: jawn-play` (discontinued) * `org.typelevel :: jawn-rojoma` (discontinued) * `org.typelevel :: jawn-spray` (discontinued) Unaffected implementations include: * `io.argonaut :: argonaut-jawn` * `io.circe :: circe-parser` * `org.typelevel :: jawn-ast` (>= 0.8.0) * `org.typelevel :: jawn-json4s` (discontinued) * `org.typelevel :: jawn-argonaut` (discontinued) ### Patches `jawn-parser-1.3.2` fixes the issue. ### Workarounds Override `objectContext()` to use a collision-safe collection. See [the patch](https://github.com/typelevel/jawn/pull/390/files) for an example in both `SimpleFacade` and `MutableFacade`. ### References * https://github.com/typelevel/jawn/pull/390 ### Credits * @kag0, for the report and the patch ### For more information If you have any questions or comments about this advisory: * Open an issue in [typelevel/jawn](https://github.com/typelevel/jawn) * E-mail a maintainer: * [@rossabaker](mailto:ross@rossabaker.com)
