CVE-2025-48988 log

Source
Severity Medium
Remote Yes
Type Denial of service
Description
Tomcat used the same limit for both request parameters and parts in a multipart request. Since uploaded parts also include headers which must be retained, processing multipart requests can result in significantly more memory usage. A specially crafted request that used a large number of parts could trigger excessive memory usage leading to a DoS. The maximum number of parts is now configurable (maxPartCount on the Connector) with a default of 10 parts.
