CVE-2025-27111

## Summary `Rack::Sendfile` can be exploited by crafting input that includes newline characters to manipulate log entries. ## Details The `Rack::Sendfile` middleware logs unsanitized header values from the `X-Sendfile-Type` header. An attacker can exploit this by injecting escape sequences (such as newline characters) into the header, resulting in log injection. ## Impact This vulnerability can distort log files, obscure attack traces, and complicate security auditing. ## Mitigation - Update to the latest version of Rack, or - Remove usage of `Rack::Sendfile`.

Rack es una interfaz modular de servidor web Ruby. El middleware Rack::Sendfile registra valores de encabezado no depurados del encabezado X-Sendfile-Type. Un atacante puede aprovechar esto inyectando secuencias de escape (como caracteres de nueva línea) en el encabezado, lo que da como resultado la inyección de registros. Esta vulnerabilidad se corrigió en 2.2.12, 3.0.13 y 3.1.11.
