Medium [CVE-2026-59897] Information disclosure due to incorrect header de-duplication in AWS API Gateway v1 adapter
CVE-2026-59897Source published Source updated
Hono is a Web application framework that provides support for any JavaScript runtime. From 4.3.3 before 4.12.27, the AWS API Gateway v1 adapter can drop a distinct repeated request header value because it de-duplicates values using a substring comparison instead of an exact match, so middleware or application logic that depends on the complete X-Forwarded-For chain, rate limiting, audit logging, or proxy-chain validation can receive incomplete data. This issue is fixed in version 4.12.27. Consequently, this could result in information disclosure or the bypass of security controls. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N). Weakness: CWE-1289.
