How to Fix CVE-2020-13955

To remediate this vulnerability, upgrade all affected Calcite 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.

org.apache.calcite:calcite-core fixed: 1.26.0
<dependency>
    <groupId>org.apache.calcite</groupId>
    <artifactId>calcite-core</artifactId>
    <version>1.26.0</version>
</dependency>
org.apache.calcite:calcite-druid fixed: 1.26.0
<dependency>
    <groupId>org.apache.calcite</groupId>
    <artifactId>calcite-druid</artifactId>
    <version>1.26.0</version>
</dependency>
org.apache.calcite:calcite-splunk fixed: 1.26.0
<dependency>
    <groupId>org.apache.calcite</groupId>
    <artifactId>calcite-splunk</artifactId>
    <version>1.26.0</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=org.apache.calcite

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-13955, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.calcite

Analyze the terminal output to locate any version of Calcite core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.26.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.calcite 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-295: Improper Certificate Validation, where the product does not validate, or incorrectly validates, a certificate. In Calcite 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.

Source Advisory Statement

"HttpUtils#getURLConnection method disables explicitly hostname verification for HTTPS connections making clients vulnerable to man-in-the-middle attacks. Calcite uses this method internally to connect with Druid and Splunk so information leakage may happen when using the respective Calcite adapters. The method itself is in a utility class so people may use it to create vulnerable HTTPS connections for other applications. From Apache Calcite 1.26 onwards, the hostname verification will be performed using the default JVM truststore."
