CVE-2026-7381 (2026-04-29)

Plack::Middleware::XSendfile versions through 1.0053 for Perl can allow client-controlled path rewriting. Plack::Middleware::XSendfile allows the variation setting (sendfile type) to be set by the client via the X-Sendfile-Type header, if it is not considered in the middleware constructor or the Plack environment. A malicious client can set the X-Sendfile-Type header to "X-Accel-Redirect" to services running behind nginx reverse proxies, and then set the X-Accel-Mapping to map the path to an arbitrary file on the server. Since 1.0053, Plack::Middleware::XSendfile is deprecated and will be removed from future releases of Plack. This is similar to CVE-2025-61780 for Rack::Sendfile, although Plack::Middleware::XSendfile has some mitigations that disallow regular expressions to be used in the mapping, and only apply the mapping for the "X-Accel-Redirect" type.

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.
