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::Handler::Apache2 - Apache 2.0 handlers to run PSGI application

SYNOPSIS

<Location />
SetHandler perl-script
PerlResponseHandler Plack::Handler::Apache2
PerlSetVar psgi_app /path/to/app.psgi
</Location>

<Perl>
use Plack::Handler::Apache2;
Plack::Handler::Apache2->preload("/path/to/app.psgi");
</Perl>

# Or create your own handler:
package My::ModPerl::Handler;
use Plack::Handler::Apache2;

sub get_app {
  # magic!
}

sub handler {
  my $r = shift;
  my $app = get_app();
  Plack::Handler::Apache2->call_app($r, $app);
}

DESCRIPTION

This is a handler module to run any PSGI application with mod_perl on Apache 2.x.

METHODS

call_app($r, $app)

The mod_perl handler in this package loads the app and calls this method. If you'd like to do something different, you can still make use of this module by preparing $r and $app in some other fashion and calling this as a class method.
