Plack::Middleware::Security::Common versions before 0.13.1 for Perl did not block header injections in request paths. The header injection rule was ineffective at blocking header injections in the request paths unless they were double-encoded, for example, GET /path\r\nHTTP/1.1\r\nHost: secret.example.com Note that it is unclear whether request paths with CRLF followed by additional headers would be blocked by reverse proxies, or how they would be processed by Plack-based servers.

Las versiones de Plack::Middleware::Security::Common anteriores a la 0.13.1 para Perl no bloqueaban las inyecciones de encabezado en las rutas de solicitud. La regla de inyección de encabezado era ineficaz para bloquear las inyecciones de encabezado en las rutas de solicitud a menos que estuvieran doblemente codificadas, por ejemplo, GET /path\r\nHTTP/1.1\r\nHost: secret.example.com Cabe señalar que no está claro si las rutas de solicitud con CRLF seguidas de encabezados adicionales serían bloqueadas por proxies inversos, o cómo serían procesadas por servidores basados en Plack.
