    Summary: Inconsistent interpretation of HTTP Requests in github.com/gin-gonic/gin

    Details: Due to improper HTTP header sanitization, a malicious user can spoof their source IP address by setting the X-Forwarded-For header. This may allow a user to bypass IP based restrictions, or obfuscate their true source.
