Summary
HTTP::Body versions before 1.23_01 for Perl are affected. The multipart parser creates a temporary file when a file part starts but adds it to the upload list only when the part completes, so a body that ends inside a file part leaves its temporary file where cleanup cannot find it (CWE-459). A remote attacker can repeat such requests to fill the temporary directory, leaving one file behind for each.

Description from the CNA
HTTP::Body versions before 1.23_01 for Perl leave the temporary file of an incomplete multipart upload on disk. The multipart parser creates a temporary file as soon as a file part starts, but adds it to the upload list only when the part completes. Uploads are only ever deleted from that list, by the cleanup option or by the caller, so a body that ends inside a file part leaves its temporary file where nothing can find it. A remote attacker can fill the temporary directory by repeating such requests, leaving one file behind for each.
