Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Commons FileUpload versions 1.0 through before 1.6, and commons-fileupload2-core versions 2.0.0-M1 through before 2.0.0-M4, are vulnerable. The source gives few details, but the flaw involves resource allocation for multipart part headers when limits are insufficient, which allows a denial of service. Users should upgrade to commons-fileupload 1.6 or commons-fileupload2-core 2.0.0-M4.
