CPANSA-Plack-2015-0202 (2015-02-02)

Fixed a possible directory traversal with Plack::App::File on Win32.

CPANSA-Plack-2014-0801 (2014-08-01)

Plack::App::File would previously strip trailing slashes off provided paths. This in combination with the common pattern of serving files with Plack::Middleware::Static could allow an attacker to bypass a whitelist of generated files

CPANSA-Plack-2013-0131 (2013-01-31)

Fixed directory traversal bug in Plack::App::File on win32 environments

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::MIME - MIME type registry

SYNOPSIS

use Plack::MIME;

my $mime = Plack::MIME->mime_type(".png"); # image/png

# register new type(s)
Plack::MIME->add_type(".foo" => "application/x-foo");

# Use MIME::Types as a fallback
use MIME::Types 'by_suffix';
Plack::MIME->set_fallback(sub { (by_suffix $_[0])[0] });

DESCRIPTION

Plack::MIME is a simple MIME type registry for Plack applications. The selection of MIME types is based on Rack's Rack::Mime module.
