How to Fix CVE-2026-43975
To remediate this vulnerability, upgrade all affected Wicket core 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.wicket</groupId>
<artifactId>wicket-core</artifactId>
<version>Latest secure release</version>
</dependency><dependency>
<groupId>org.apache.wicket</groupId>
<artifactId>wicket-core</artifactId>
<version>Latest secure release</version>
</dependency><dependency>
<groupId>org.apache.wicket</groupId>
<artifactId>wicket-core</artifactId>
<version>10.9.0</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.wicketHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-43975, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.wicketAnalyze the terminal output to locate any version of Wicket core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 10.9.0), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.wicket 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Wicket core, 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.
