Summary
Plack::Middleware::XSendfile versions through 1.0053 for Perl can allow client-controlled path rewriting
Details

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.
