Live › vulnerability › CVE-2026-116132
Go to dashboardHTTP::Body, a Perl module for parsing request bodies, creates a temporary file for a multipart file part but never records it when the upload ends early, so the file is never cleaned up. A remote attacker can repeat such requests to fill the temporary directory.
Summary written from the sources below. Check the originals before acting.

Perl web applications that accept multipart file uploads and parse them with HTTP::Body, including applications that get it indirectly through a framework, are exposed. Applications that do not accept file uploads, or that run behind a front end which rejects or limits multipart bodies, are much less exposed. Teams that do not run Perl web code can skip it.

perl -MHTTP::Body -e 'print $HTTP::Body::VERSION'HTTP::Body line with a version below 1.23_01 in the cpanfile, cpanfile.snapshot or Makefile.PL of each Perl application1.23_01 or laterEach row is the first time that source carried this signal. The analyst’s rows are its own findings.
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.
