Gakido is a Python HTTP client focused on browser impersonation and anti-bot evasion. A vulnerability was discovered in Gakido prior to version 0.1.1 that allowed HTTP header injection through CRLF (Carriage Return Line Feed) sequences in user-supplied header values and names. When making HTTP requests with user-controlled header values containing "\r\n" (CRLF), "\n" (LF), or "\x00" (null byte) characters, an attacker could inject arbitrary HTTP headers into the request. The fix in version 0.1.1 adds a "_sanitize_header()" function that strips "\r", "\n", and "\x00" characters from both header names and values before they are included in HTTP requests.
