CVE-2025-48976
Good to know:
Date: June 16, 2025
Apache Commons FileUpload provided a hard-coded limit of 10kB for the size of the headers associated with a multipart request. A specially crafted request that used a large number of parts with large headers could trigger excessive memory usage leading to a DoS. This limit is now configurable (maxPartHeaderSize on the Connector) with a default of 512 bytes.
