Summary
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.

Impact
CVE-2025-66033 has a CVSS score of 5.3 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (24.0.1); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-66033? CVE-2025-66033 is a medium-severity security vulnerability in com.okta.sdk:okta-sdk-root (maven), affecting versions >= 21.0.0, <= 24.0.0. It is fixed in 24.0.1.
- How severe is CVE-2025-66033? CVE-2025-66033 has a CVSS score of 5.3 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of com.okta.sdk:okta-sdk-root are affected by CVE-2025-66033? com.okta.sdk:okta-sdk-root (maven) versions >= 21.0.0, <= 24.0.0 is affected.
- Is there a fix for CVE-2025-66033? Yes. CVE-2025-66033 is fixed in 24.0.1. Upgrade to this version or later.
- Is CVE-2025-66033 exploitable, and should I be worried? Whether CVE-2025-66033 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-66033 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2025-66033? Upgrade
com.okta.sdk:okta-sdk-rootto 24.0.1 or later.
