How to Fix GHSA-q95j-488q-5q3p

To remediate this vulnerability, upgrade all affected Apiman manager api impl 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.apiman:apiman-manager-api-impl fixed: 3.0.0.Final 
<dependency>
    <groupId>io.apiman</groupId>
    <artifactId>apiman-manager-api-impl</artifactId>
    <version>3.0.0.Final</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.apiman

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-q95j-488q-5q3p, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.apiman

Analyze the terminal output to locate any version of Apiman manager api impl in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.0.Final), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.apiman 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-787: Out-of-bounds Write, where the product writes data past the end, or before the beginning, of the intended buffer. In Apiman manager api impl, 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 Due to a vulnerability in `jackson-databind <= 2.12.6.0`, an authenticated attacker could craft an Apiman policy configuration which, when saved, may cause a denial of service on the Apiman Manager API. This does **not** affect the Apiman Gateway. ### Patches Upgrade to Apiman 3.0.0.Final or later. If you are using an older version of Apiman and need to remain on that version, contact your Apiman [support provider](https://www.apiman.io/support.html) for advice/long-term support. ### Workarounds If all users of the Apiman Manager are trusted then you may assess this is low risk, as an account is required to exploit the vulnerability. ### References * Apiman maintainer and security contact: marc@blackparrotlabs.io * https://nvd.nist.gov/vuln/detail/CVE-2020-36518 * https://github.com/FasterXML/jackson-databind/issues/2816
