         CVE ID:  CVE-2026-116134

   Distribution:  HTTP-Body
       Versions:  before 1.23_01

HTTP::Body versions before 1.23_01 for Perl allow memory exhaustion via
an unbounded multipart part header block

Description
-----------
HTTP::Body versions before 1.23_01 for Perl allow memory exhaustion via
an unbounded multipart part header block.

The multipart parser takes everything up to the first blank line after
a boundary as the part's header block, with no limit on its size or
number of lines. Every line is stored in the part's header hash, so a
block of short lines costs about 60 bytes of memory per input byte.

A remote attacker can exhaust worker memory with a single request.

Problem types
-------------
- CWE-770 Allocation of Resources Without Limits or Throttling

Solutions
---------
Upgrade to HTTP-Body 1.23_01 or later.
