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::Middleware::Restarter - Restart the standalone server

SYNOPSIS

DEPRECATED. Use Plack::Loader::Reloadble or plackup's -r option.

DESCRIPTION

This middleware forks the main standalone server and creates a watcher that watches the filesystem in the current directory and restarts the server process by sending HUP when it finds an updated file. This middleware might be handy for a quick restart in the development but not recommended to use on the production environment.

CONFIGURATION

directories
enable "Plack::Middleware::Restarter",
    directories => "/path/to/app";

Specifies which directory to watch for file updates. Defaults to . (current directory).

filter
enable "Plack::Middleware::Restarter",
    filter => qr/\.pm$/;

The regular expression filter to match what files to watch for updates. Defaults to \.(pm|yml|yaml|conf|psgi)$.

PORTABILITY

This module might not work on Win32/VMS systems.
