When a Multipart request is performed but some of the fields exceed the maxStringLength limit, the upload files will remain in struts.multipart.saveDir even if the request has been denied.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.34%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
