{"id":"CVE-2026-24489","state":"PUBLISHED","title":"Gakido vulnerable to HTTP Header Injection (CRLF Injection)","description":"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.","publishedAt":"2026-01-27T00:36:34.230Z","updatedAt":"2026-01-27T14:46:42.530Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["HappyHackingSpace gakido"],"affected":[{"vendor":"HappyHackingSpace","product":"gakido","versions":[{"version":"< 0.1.1","status":"affected"}]}],"references":["https://github.com/HappyHackingSpace/gakido/security/advisories/GHSA-gcgx-chcp-hxp9","https://github.com/HappyHackingSpace/gakido/commit/369c67e67c63da510c8a9ab021e54a92ccf1f788","https://github.com/HappyHackingSpace/gakido/releases/tag/v0.1.1-1bc6019"],"weaknesses":["CWE-93","CWE-113"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/24xxx/CVE-2026-24489.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-24489","state":"PUBLISHED","datePublished":"2026-01-27T00:36:34.230Z","dateUpdated":"2026-01-27T14:46:42.530Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-01-23T00:38:20.548Z"},"containers":{"cna":{"title":"Gakido vulnerable to HTTP Header Injection (CRLF Injection)","descriptions":[{"lang":"en","value":"Gakido is a Python HTTP client focused on browser impersonation and anti-bot evasion.
