Description Pedro Sampaio 2023-12-05 10:28:43 UTC 
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.
Users are recommended to upgrade to versions Struts 2.5.32 or 6.1.2.2 or Struts 6.3.0.1 or greater, which fixe this issue.
