CVE-2023-26125 (opens in a new tab)How to fix?
Upgrade github.com/gin-gonic/gin to version 1.9.0 or higher.
Overview
github.com/gin-gonic/gin is a package that implements a HTTP web framework called gin.
Affected versions of this package are vulnerable to Improper Input Validation by allowing an attacker to use a specially crafted request via the X-Forwarded-Prefix header, potentially leading to cache poisoning.
Note: Although this issue does not pose a significant threat on its own it can serve as an input vector for other more impactful vulnerabilities. However, successful exploitation may depend on the server configuration and whether the header is used in the application logic.
