Security Impact
CVSS: 4.9
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:U/C:H/I:N/A:N).
How to Fix CVE-2026-42797
To remediate this vulnerability, upgrade all affected Syncope core provisioning api dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.syncope.core</groupId>
<artifactId>syncope-core-provisioning-api</artifactId>
<version>Latest secure release</version>
</dependency><dependency>
<groupId>org.apache.syncope.core</groupId>
<artifactId>syncope-core-provisioning-api</artifactId>
<version>4.0.6</version>
</dependency><dependency>
<groupId>org.apache.syncope.core</groupId>
<artifactId>syncope-core-provisioning-api</artifactId>
<version>4.1.1</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.syncope.coreHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-42797, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.syncope.coreAnalyze the terminal output to locate any version of Syncope core provisioning api in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.6), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.syncope.core 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-202: Exposure of Sensitive Information Through Data Queries, where when trying to keep information confidential, an attacker can often infer some of the information by using statistics. In Syncope core provisioning api, software state validation or input boundaries are circumvented during processing.
