There is no fixed version for Echo:latest golang-github-labstack-echo.
NVD Description
Note: Versions mentioned in the description apply only to the upstream golang-github-labstack-echo package and not the golang-github-labstack-echo package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
Echo is a Go web framework. From 4.0.0 until 5.1.0, Context.RealIP falls back to client-supplied X-Forwarded-For or X-Real-IP values when Echo.IPExtractor is unset, and the default RateLimiter uses that result as its client identifier. A remote attacker can rotate arbitrary forwarded-address values to obtain new rate-limit buckets and bypass IP-based throttling used for controls such as brute-force or request-volume protection. This issue is fixed in Echo v5.1.0.
