Source description

As published by the source; long descriptions are shortened.

Allocation of Resources Without Limits or Throttling vulnerability in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M20, from 10.1.0-M1 through 10.1.24, from 9.0.13 through 9.0.89. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.35 through 8.5.100 and 7.0.92 through 7.0.109. Users are recommended to upgrade to version 11.0.0-M21, 10.1.25, or 9.0.90, which fixes the issue. Apache Tomcat, under certain configurations on any platform, allows an attacker to cause an OutOfMemoryError by abusing the TLS handshake process.

# Patch Next advisory brief: CVE-2024-38286

Advisory: Apache Tomcat Allocation of Resources Without Limits or Throttling vulnerability
IDs: CVE-2024-38286, GHSA-7jqf-v358-p8g7
Record: https://patchnext.com/advisories/cve-2024-38286 (revision 1, source checked 26 Oct 2026, 16:54 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.apache.tomcat:tomcat-coyote 11.0.0-M21, 10.1.25, 9.0.90; org.apache.tomcat.embed:tomcat-embed-core 11.0.0-M21, 10.1.25, 9.0.90. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.tomcat:tomcat-coyote: affected >= 11.0.0-M1, < 11.0.0-M21; >= 10.1.0-M1, < 10.1.25; >= 9.0.13, < 9.0.90; >= 8.5.35, <= 8.5.100; >= 7.0.92, <= 7.0.109; fixed in 11.0.0-M21, 9.0.90, 10.1.25
- Maven org.apache.tomcat.embed:tomcat-embed-core: affected >= 11.0.0-M1, < 11.0.0-M21; >= 10.1.0-M1, < 10.1.25; >= 9.0.13, < 9.0.90; >= 8.5.35, <= 8.5.100; >= 7.0.92, <= 7.0.109; fixed in 11.0.0-M21, 9.0.90, 10.1.25

## Suggested inspection (read-only)
- Maven org.apache.tomcat:tomcat-coyote: check the installed version with your package manager.
- Maven org.apache.tomcat.embed:tomcat-embed-core: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.apache.tomcat:tomcat-coyote, org.apache.tomcat.embed:tomcat-embed-core.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
