How to Fix CVE-2025-66033

To remediate this vulnerability, upgrade all affected Okta sdk root dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.okta.sdk:okta-sdk-root fixed: 24.0.1 
<dependency>
    <groupId>com.okta.sdk</groupId>
    <artifactId>okta-sdk-root</artifactId>
    <version>24.0.1</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=com.okta.sdk

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-66033, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.okta.sdk

Analyze the terminal output to locate any version of Okta sdk root in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 24.0.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.okta.sdk 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-401: Missing Release of Memory after Effective Lifetime, where the product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse. In Okta sdk root, 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

### Description In the Okta Java SDK, specific multithreaded implementations may encounter memory issues as threads are not properly cleaned up after requests are completed. Over time, this can degrade performance and availability in long-running applications and may result in a denial-of-service condition under sustained load. ### Affected product and versions You may be affected by this vulnerability if you meet the following preconditions: - Using the Okta Java SDK between versions 21.0.0 and 24.0.0, and - Implementing a long-running application using the ApiClient in a multi-threaded manner. ### Resolution Upgrade Okta/okta-sdk-java to versions 24.0.1 or greater. ### Acknowledgement Okta would like to thank Andrew Pikler (pyckle) for their discovery and responsible disclosure.
