3DescriptionGitHub Advisory
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.
AnalysisAI
HTTP header injection in the Gakido Python HTTP client prior to version 0.1.1 allows unauthenticated attackers to inject arbitrary headers into requests by embedding CRLF or null byte sequences in user-supplied header values and names. An attacker could leverage this to manipulate HTTP requests and potentially bypass security controls or perform request smuggling attacks. The vulnerability has been patched in version 0.1.1 with header sanitization functions, though no patch is currently available for affected systems.
