What is CVE-2026-116134?

CVE-2026-116134 is a vulnerability, published on 28 Oct 2026.

Official 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.

Weakness: CWE-770
