Vulnerability from github – Published: 2026-10-15 12:31 – Updated: 2026-10-15 18:32

Details

In api-gateway versions till 1.7.3, The default rate-limit key resolver, ClientIpKeyResolver, derives the per-client bucket key from the leftmost element of the X-Forwarded-For request header. That element is supplied by the originating HTTP client and is not validated against any trusted-proxy list. A single attacker can therefore obtain an unlimited number of independent rate-limit buckets — one per unique header value — and completely bypass the gateway's request-rate limiting on every route that uses the shipped default configuration.

Severity

6.5 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Vulnerability from cvelistv5 – Published: 2026-10-15 11:58 – Updated: 2026-10-15 15:30

Summary

In `api-gateway` versions till `1.7.3`, The default rate-limit key resolver, `ClientIpKeyResolver`, derives the per-client bucket key from the leftmost element of the `X-Forwarded-For` request header. That element is supplied by the originating HTTP client and is not validated against any trusted-proxy list. A single attacker can therefore obtain an unlimited number of independent rate-limit buckets — one per unique header value — and completely bypass the gateway's request-rate limiting on every route that uses the shipped default configuration.
