AI-suggested
A fix is available. Users should upgrade to Apache Tomcat versions 11.0.12 or later, 10.1.47 or later, or 9.0.110 or later to resolve this issue. No other mitigation actions are specifically recommended by the vendor advisory.
Description
Apache Tomcat versions from 9.0.0 through 9.0.109, 10.1.0 through 10.1.46, and 11.0.0 through 11.0.11 have a vulnerability where temporary files from multipart uploads are not immediately cleaned up if an error occurs. This delayed cleanup can cause disk space exhaustion leading to denial of service (DoS). The issue affects some older EOL versions as well. Fixed versions are 9.0.110 or later, 10.1.47 or later, and 11.0.12 or later.
