Plack-1.0055
⭐ Starred 488 / Plack::LWPish
Security Advisories (1)
CVE-2026-115825 (2026-10-25)

HTTP::Server::PSGI versions before 1.0056 for Perl allow a single request to crash the server by declaring a large Content-Length. The request body is read with sysread() calls sized by the remaining Content-Length. Perl grows the read buffer to the requested length before any data arrives, so the server tries to allocate as much memory as the client declares. A remote attacker can send one request with a large Content-Length and a few body bytes, and perl exits with an out-of-memory error before the application is called. HTTP::Server::PSGI runs as a single process, so the server stays down until restarted.

NAME

Plack::LWPish - HTTP::Request/Response compatible interface with HTTP::Tiny backend

SYNOPSIS

use Plack::LWPish;

my $request = HTTP::Request->new(GET => 'http://perl.com/');

my $ua = Plack::LWPish->new;
my $res = $ua->request($request); # returns HTTP::Response

DESCRIPTION

This module is an adapter object that implements one method, request that acts like LWP::UserAgent's request method i.e. takes HTTP::Request object and returns HTTP::Response object.

This module is used solely inside Plack::Test::Suite and Plack::Test::Server, and you are recommended to take a look at HTTP::Thin if you would like to use this outside Plack.
