How to Fix CVE-2019-10094

To remediate this vulnerability, upgrade all affected Tika 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.tika:tika-core fixed: 1.22 
<dependency>
    <groupId>org.apache.tika</groupId>
    <artifactId>tika-core</artifactId>
    <version>1.22</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.tika

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-10094, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Tika core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.22), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.tika 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-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Tika 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

A carefully crafted package/compressed file that, when unzipped/uncompressed yields the same file (a quine), causes a StackOverflowError in Apache Tika's RecursiveParserWrapper in versions 1.7-1.21. Apache Tika users should upgrade to 1.22 or later.
