In versions up to and including 3.7.8, a CRLF (Carriage Return Line Feed) injection vulnerability exists in the construction and output of HTTP headers within `AsyncWebHeader.cpp`. Unsanitized input allows attackers to inject CR (`\\r`) or LF (`\\n`) characters into header names or values, leading to arbitrary header or response manipulation. Manipulation of HTTP headers and responses can enable a wide range of attacks, making the severity of this vulnerability high. A fix is available at pull request 211 and is expected to be part of version 3.7.9."},{"lang":"es","value":"ESPAsyncWebServer es una librería de servidor HTTP y WebSocket asíncrono para ESP32, ESP8266, RP2040 y RP2350.
