CyberRota Analysis
AI-GeneratedThe AWS API Gateway v1 adapter in Hono versions prior to 4.12.27 is vulnerable due to improper handling of repeated request header values, which can lead to incomplete data being processed in middleware or application logic. This flaw may impact functionalities such as rate limiting, audit logging, and proxy-chain validation, potentially compromising the integrity of data handling. Organizations using affected versions should prioritize updating to 4.12.27 to mitigate these risks.

Original NVD Description
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.
