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::App::WrapCGI - Compiles a CGI script as PSGI application

SYNOPSIS

use Plack::App::WrapCGI;

my $app = Plack::App::WrapCGI->new(script => "/path/to/script.pl")->to_app;

# if you want to execute as a real CGI script
my $app = Plack::App::WrapCGI->new(script => "/path/to/script.rb", execute => 1)->to_app;

DESCRIPTION

Plack::App::WrapCGI compiles a CGI script into a PSGI application using CGI::Compile and CGI::Emulate::PSGI, and runs it with any PSGI server as a PSGI application.

See also Plack::App::CGIBin if you have a directory that contains a lot of CGI scripts and serve them like Apache's mod_cgi.

METHODS

new
my $app = Plack::App::WrapCGI->new(%args);

Creates a new PSGI application using the given script. %args has two parameters:

script

The path to a CGI-style program. This is a required parameter.

execute

An optional parameter. When set to a true value, this app will run the script with a CGI-style fork/exec model. Note that you may run programs written in other languages with this approach.
