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.

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

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

NAME

Plack::Middleware::AccessLog::Timed - Logs requests with time and accurate body size

SYNOPSIS

# in app.psgi
use Plack::Builder;

builder {
    enable "Plack::Middleware::AccessLog::Timed",
        format => ""%v %h %l %u %t \"%r\" %>s %b %D";
    $app;
};

DESCRIPTION

Plack::Middleware::AccessLog::Timed is a subclass of Plack::Middleware::AccessLog but uses a wrapped body handle to get the actual response body size %b (even if it's not a chunk of array or a real filehandle) and the time taken to serve the request: %T or %D.

This wraps the response body output stream so some server optimizations like sendfile(2) will be disabled if you use this middleware.

CONFIGURATION

Same as Plack::Middleware::AccessLog.
