What is CVE-2026-32588?

CVE-2026-32588 is a low-severity uncontrolled resource consumption vulnerability in org.apache.cassandra:cassandra-all (maven), affecting versions >= 4.0, < 4.0.20. It is fixed in 4.0.20, 4.1.11, 5.0.7. Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service.

Which versions of org.apache.cassandra:cassandra-all are affected by CVE-2026-32588?

org.apache.cassandra:cassandra-all (maven) versions >= 4.0, < 4.0.20 is affected.

Is there a fix for CVE-2026-32588?

Yes. CVE-2026-32588 is fixed in 4.0.20, 4.1.11, 5.0.7. Upgrade to this version or later.

Is CVE-2026-32588 exploitable, and should I be worried?

Whether CVE-2026-32588 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-2026-32588 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.

Summary

Authenticated DoS over CQL in Apache Cassandra 4.0, 4.1, 5.0 allows authenticated user to raise query latencies via repeated password changes.
Users are recommended to upgrade to version 4.0.20, 4.1.11, 5.0.7, which fixes this issue.

Impact

Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service. Typical impact: denial of service.

Affected versions

org.apache.cassandra:cassandra-all (>= 4.0, < 4.0.20) org.apache.cassandra:cassandra-all (>= 4.1, < 4.1.11) org.apache.cassandra:cassandra-all (>= 5.0, < 5.0.7)

Security releases

org.apache.cassandra:cassandra-all → 4.0.20 (maven) org.apache.cassandra:cassandra-all → 4.1.11 (maven) org.apache.cassandra:cassandra-all → 5.0.7 (maven)

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.
