How to Fix CVE-2022-33879

To remediate this vulnerability, upgrade all affected Tika 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 fixed: 1.28.4 
<dependency>
    <groupId>org.apache.tika</groupId>
    <artifactId>tika</artifactId>
    <version>1.28.4</version>
</dependency>
org.apache.tika:tika fixed: 2.4.1 
<dependency>
    <groupId>org.apache.tika</groupId>
    <artifactId>tika</artifactId>
    <version>2.4.1</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-2022-33879, 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 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.28.4), 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 General Security Weakness. In Tika, 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

The initial fixes in CVE-2022-30126 and CVE-2022-30973 for regexes in the StandardsExtractingContentHandler were insufficient, and we found a separate, new regex DoS in a different regex in the StandardsExtractingContentHandler. These are now fixed in 1.28.4 and 2.4.1.
