CVE-2026-110726: Eclipse Foundation Eclipse Connected Services Platform

Medium severity, CVSS 6.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Eclipse Foundation Eclipse Connected Services Platform: from 1.5.4, up to and including 1.7.3
