CVE-2024-52317

Incorrect object re-cycling and re-use vulnerability in Apache Tomcat. Incorrect recycling of the request and response used by HTTP/2 requests could lead to request and/or response mix-up between users.

This issue affects Apache Tomcat: from 11.0.0-M23 through 11.0.0-M26, from 10.1.27 through 10.1.30, from 9.0.92 through 9.0.95.

Users are recommended to upgrade to version 11.0.0, 10.1.31 or 9.0.96, which fixes the issue.

CVE-2024-52317 has a CVSS score of 6.5 (Medium). The vector is network-reachable, no 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 (9.0.96, 10.1.31, 11.0.0); upgrading removes the vulnerable code path.

2. How severe is CVE-2024-52317? CVE-2024-52317 has a CVSS score of 6.5 (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.
3. Which packages are affected by CVE-2024-52317?
   • org.apache.tomcat.embed:tomcat-embed-core (maven) (versions >= 9.0.92, < 9.0.96)
   • org.apache.tomcat:tomcat-coyote (maven) (versions >= 9.0.92, < 9.0.96)
4. Is there a fix for CVE-2024-52317? Yes. CVE-2024-52317 is fixed in 9.0.96, 10.1.31, 11.0.0. Upgrade to this version or later.
5. Is CVE-2024-52317 exploitable, and should I be worried? Whether CVE-2024-52317 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.

6. What actually determines whether CVE-2024-52317 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.
7. How do I fix CVE-2024-52317?
   • Upgrade org.apache.tomcat.embed:tomcat-embed-core to 9.0.96 or later
   • Upgrade org.apache.tomcat:tomcat-coyote to 9.0.96 or later
